Building wheel for python-ldap (setup.py) ... error(fatal error: 'sasl.h' file not found,command 'gcc' failed with exit status 1) [duplicate]

Please don't call this a duplicate.
All the answers have so far only 'solved' the problem by installing the ldap and other development packages globally, which doesn't solve the problem of not being able to install the python-ldap package in the virtual environment.
Examples include:
How do I install python-ldap in a virtualenv on Ubuntu?
sudo apt-get install libsasl2-dev python-dev libldap2-dev libssl-dev
I am using ubuntu 14.04, python 2.7 and flask in my virtual environment.
When I run pip install python-ldap, I receive the following error.

If I try to pip install any of the suggested dev libraries so that they are inside my virtual environment, I get the following error.
Could not find a version that satisfies the requirement libsasl2-dev (from versions: ) No matching distribution found for libsasl2-dev
I can install all this stuff globally just fine, but that just plain defeats the purpose of using virtualenv.
I would really like to find a meaningful, virtualenv solution, since all I have been able to find is non-virtualenv solutions for a virtualenv question.
Thanks.

The Python package python-ldap requires some other libs (libsasl2-dev, …) which are not python libs (so you can't use pip to install them). So, to use them, you have to install them. Two solutions:
use your package manager to install them (ex.: apt-get) ;
download their source code and compile them locally (in your virtualenv) (useful for some libs in special cases).
Maybe you can try the second solution?

I'm using the buildpack: python 1.5.5
My runtime.txt contains: python-3.5.0
How can I install the necessary headers in the buildpack?
Update:
It looks as though the latest cloud foundry stack has the sasl library: https://github.com/cloudfoundry/cflinuxfs2/blob/1.119.0/cflinuxfs2/build/install-packages.sh#L98.
How can I use this stack on Bluemix?

Maybe you should install some system libraries before you can install sasl refer to https://pypi.python.org/pypi/sasl/0.1.3
This library contains C++ code, and will require some additional
system libraries installed.
Debian/Ubuntu
apt-get install python-dev libsasl2-dev gcc
CentOS/RHEL
yum install gcc-c++ python-devel.x86_64
cyrus-sasl-devel.x86_64

The solution for me was to use pure-sasl and install imypla and thrift_sasl from application code rather than my requirements.txt:
try:
import impyla
except ImportError:
print("Installing missing impyla")
import pip
pip.main(['install', '--no-deps', 'impyla'])
try:
import thrift_sasl
except ImportError:
print("Installing missing thrift_sasl")
import pip
# need a patched version of thrift_sasl. see https://github.com/cloudera/impyla/issues/238
pip.main(['install', '--no-deps', 'git+https://github.com/snowch/thrift_sasl'])
I added this code to a view in my flask application: https://github.com/snowch/movie-recommender-demo/blob/master/web_app/app/main/views.py

I was having similar error -
In file included from sasl/saslwrapper.cpp:254:0:

biopython installation: error: command 'gcc' failed with exit status 1

I am trying to install the python package biopython from source on my Macbook pro OSX 10.9.4,
I run python setup.py build in the terminal and receive this

I checked that Xcode should be properly installed and working

You should be using pip. Try:
pip install biopython

Uninstalled Canopy and everything worked like a charm...

Try installing the Biopython version available from the Canopy "Package Manager" > "Available Packages" > "Canopy Packages".
This way, I seem to have solved a similar problem while installing Pyensembl, that also installs Biopython.

Why can't I install greenlet (just a basic python package)?

I untarred it from: http://pypi.python.org/pypi/greenlet#downloads
(I'm in my virtual env. I sourced it, too, thats why I didn't sudo)

On Ubuntu you'd need to install the python-dev package. This provides the Python.h header:
% dpkg -S /usr/include/python2.6/Python.h
python2.6-dev: /usr/include/python2.6/Python.h

you don't have python-dev installed so there is no Python.h header.

Error building 'lxml.etree' extension

I'm trying to install lxml, on an Ubuntu server running Python 2.6 (in a virtualenv - the system Python is 2.5).
I've checked out via svn and as a result I've also install Cython, as per the instructions.
However, I get the following error when running python setup.py build:

And very similar errors if i try python setup.py bdist_egg, python setup.py build_ext -i or make
Trying to install via easy_install or pip produces the same error - although the former just hangs indefinitely.
As far as I am aware, all of the various dependencies, such as python-dev are installed.
What am I missing / doing wrong?

You appear to be on the bleeding edge. Suggestions: Use a released version of the lxml source. Consult with the lxml author/maintainer.
