OSX: pyosmium setup error

I'm running a setup Python script for Pyosmium on OSX 10.11, Python version is 2.7:
python setup.py install
running install
running build
running build_py
running build_ext
building 'osmium._osmium' extension

In file included from lib/osmium.cc:1:
../libosmium/include/osmium/visitor.hpp:36:10: fatal error: 'type_traits' file not found
As far as possible I've most available dependencies using Brew. And added required directories for supporting developments.
Though it's clear I am dealing with a level here that I am not at all familiar with.
My guess at the moment is the compiler that's been called - gcc, should this be Any ideas would be much appreciated!
Thank you,

Centos 5 Python 2.7, Cannot install Python-LDAP

I need to install
* Python-LDAP
to run under Ptython 2.7
I have a Centos 5.8 system (I cannot upgrade to 6.x). I currently have Python 2.4 installed and also Python 2.7. I am using Python 2.7 for development (along with Django). I have Python-LDAP installed and working under Python 2.4 (it was installed using yum). I need to install Python-LDAP for use with Python 2.7 (I will also install Django-ldap). I have been trying for days to do this. yum only runs under Python 2.4 so I cannot use that. I downloaded the Python-LDAP source (python-ldap-2.4.13.tar.gz (md5) from https://pypi.python.org/pypi/python-ldap/ but when I try to build it I get errors (see below).
Does anyone know if/how I can install Python-LDAP for Python 2.7 on Centos 5?

I then looked over at this thread: https://mail.python.org/pipermail/python-ldap/2011q2/002937.html
So I downloaded the latest OpenLDAP and got:
./configure
Configuring OpenLDAP 2.4.38-Release ...
...
configure: error: BerkeleyDB version incompatible with BDB/HDB backends
Seems like I'm just sinking lower into a black hole...

This worked in centos 5.10 and python 2.7.6. I installed into a virtualenv.
I see mentions of evolution-openldap in your logs which were in mine when I had the same issue. Those directories are installed by openldap 2.3x.
You don't need to build openldap from source as there is a version in yum that is new enough to satisfy the version requirement by python-ldap.
openldap24-libs.i386 2.4.23-5.el5
openldap24-libs.x86_64 2.4.23-5.el5
openldap24-libs-devel.i386 2.4.23-5.el5
openldap24-libs-devel.x86_64 2.4.23-5.el5
To install you should first yum install openldap24-libs openldap24-libs-devel.
edit setup.cfg so its [_ldap] section so it contains:
library_dirs = /usr/lib/openldap24
include_dirs = /usr/include/openldap24
Run the build again. (I deleted my old build/ directory, you probably don't need to but give that a shot if the above is not working).

You are missing the python development headers, needed to build packages that need to compile extensions.
If you are building on OSX, make sure you either install a prebuilt mac python package or if building python from source, use the framework flag when configuring. And also make sure you have XCODE installed so that you have a compiler.
If you are building on Linux, you probably need to install the python devel headers. For instance on Ubuntu you would need: apt-get install build-essential python-dev.
Once you have the python development headers, twisted should be able to find them when you build with that python interpreter.

GDAL install on Mac OS X Lion

Homebrew works great for me. To install GDAL 1.9 with Homebrew all you have to do is
brew install gdal
Homebrew requires xcode, and I think commandline tools. More information can be found here

How about using the precompiled binaries available from http://www.kyngchaos.com/software/frameworks
Also, are you using 1.7.1 for a specific reason? 1.8.1 is, I believe, the current release build.
Caveat: I do not know if Lion is yet supported by the GDAL OSX binaries.

Did you actually install Xcode 4.1 on 10.7? Downloading it from the App Store is not enough; you have to manually run the Installer which it downloads to /Applications.

If you actually want to build from source, but want a convenient way to install there is a gdal package available from MacPorts - just install MacPorts, then on the command line type:
port install gdal
Macports will fetch and compile the source code for you. As of the time of writing the version in MacPorts is 1.9.0

for installing GDAL on mac:
brew install gdal
and then
pip install gdal
solved this for me
