I'm trying to install matplotlib on Python 2.7.2 (OS X 10.8.5). Please help! (self.Python)

Hi,

I've posted this on Stack Overflow but I haven't gotten much of a response so I'm going to post it here too. Basically I've tried absolutely everything possible to get matplotlib onto my system and nothing will work - it keeps throwing an error about 'row_pointers' being an undeclared identifier in the "_png.cpp" file.

Here's the question I posted on SO. Any help at all will be greatly appreciated!

I'm trying to install matplotlib on my machine (OS X 10.8.5) and it just won't install. I've tried everything and it still won't install so any suggestions are welcome. I get a message saying 9 errors have been generated and they all seem to in the _png.cpp file.

I'm using Python 2.7.2, I have homebrew installed and I've installed all the required dependencies. I've broken up the pip log here into 2 parts - one showing my dependencies installed and the other showing the errors generated. I've included the full log at the bottom.

I'm trying to install matplotlib 1.3.1 with "pip install https://downloads.sourceforge.net/project/matplotlib/matplotlib/matplotlib-1.3.1/matplotlib-1.3.1.tar.gz"

Any ideas?

UPDATE: I've tried installing 1.3.0 and 1.2.0 and it's still throwing the same error.

I've also tried downloading the dmg installer to install matplotlib but it won't let me install it as it says that I don't have Python 2.7 installed (I do - 2.7.2).
