can not install psycopg2 2.5+ on mac osx 10.9

Here is the error log:

Any suggestions? any workaround? I am entirely blocked by this for about a day.

This one works for me:
export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments
clang error: unknown argument: '-mno-fused-madd' (python package installation failure)

Try:
sudo ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future pip install psycopg2

Im pretty sure pyscopg2 doesnt support 9.3 yet. Here's the documentation http://initd.org/psycopg/docs/news.html
I see references for 9.1 and 9.2 but nothing for 9.3 especially since it was just released a few months ago. 9.3 incorporates it's own Foreign Writable wrapper which other modules like Multicorn now utilize.
http://www.postgresql.org/about/news/1481/
I could be wrong, just a possibility. Try using 9.2 and see if it works.

Python: Xcode no longer allows pip install mysql-python. Workaround Needed

I'm having major issues this morning trying to install mysql-python connector on the Mac.
The issues is down to a recent update to xcode 5.1:

http://forums.getpebble.com/discussion/11862/installation-error-perhaps-due-to-xcode-5-1
However, I have tried the current work-around and I still get the error:
This is what I have tried:
ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future sudo pip install mysql-python
This is the error:

Anyone had the same issue and know of a workaround that works in your virtual env?

I wrote the post on your first link. I am not 100% percent sure but I think the problem lies with the use of sudo. The variable is set under your user, while the pip command is elevated to root privileges, i.e. is executed under another user. Try to do the above logged in as root user from the start, without sudoing.

Help Please

You probably need Xcode's Command Line Tools.
Download the lastest version of Xcode, then go to "Preferences", select "Download" tab, then install Command Line Tools.

Can't run mongod command after got pymongo installed from pip

I'm running a virtualenv on osx 10.7.4, and I was trying to install MongoDB for python, which is version 2.7.3.
I just installed it from pip, and am trying to see what happens if I run mongod command, but it turns out I can't run the command.
Below is what happened in my terminal, could anyone give a hand here about what could be wrong?

Thanks guys!!

I think maybe you're confusing the python mongo driver with the mongo server itself.
Did you install mongodb (mongod, mongo, etc.), or just pymongo?
There's a homebrew package for mongodb, just in case you want an easy way to install it--or you can download it directly from http://www.mongodb.org/downloads.

Installing PIL on MAC OS X LION 10.7.2 with PIP INSTALLER

Any clues what the problem might be ?
I have Mac OS X Lion and LLVM is installed in the XCODE Developer tools... What can be wrong ?

i got the same error.
but additionally need to install the "commandline tools" under settings
edit:
just a few keywords for google, if someone is looking for this!
easy_install pip gcc not found mac osx xcode
may be a moderator add this keywords to the question

Are you sure you have actually run the Xcode installer (usually found in /Applications)? Downloading it from the Mac App Store doesn't automatically run the installer.

Check that you have installed XCode. Try installing a PIL from homebrew package manager
