Installing MatplotLib in mac osx lion
This is because of a change in the API for libpng v1.5 (which is included with Mac OSX Lion). The changes has already been pushed upstream, so you will need to compile from the upstream repository until the next release.
You can follow the instructions on http://jholewinski.wordpress.com/2011/07/21/installing-matplotlib-on-os-x-10-7-with-homebrew/
I followed this page's instructions. I got stuck at
pip install -e git+https://github.com/matplotlib/matplotlib#egg=matplotlib-devThen I did:
git clone https://github.com/matplotlib/matplotlib.gitcd matplotlibpython setup.py buildpython setup.py installChecked my installation by typing in terminal:
pythonimport matplotlibprint matplotlib.__version__print matplotlib.__file__I got version 0.10.0 dev (as of this writing) and path /usr/local/Cellar/...
You can try with an "official" python distribution, apple might have tweaked the supplied one. You can find the 2.7 here: http://www.python.org/download/ You might have to re-install numpy as well afterwords: http://sourceforge.net/projects/numpy/files/NumPy/1.6.1/
I would suggest to install scipy as well Let me know if it works ;)
