I was trying to install matplotlib in Mac OSX Lion. Tried to used the binary that is in the sourcefourge site, but I got this error: "matplotlib requires System Python 2.7 to install".
I went to the Terminal and typed python --version and its check the requirements.
After this I tried to used the pip, and while doing so é got the following error:
"src/_image.cpp:908: error: invalid use of incomplete type ‘struct png_info_def’"
Can you give me clues in how to install it?
Many thanks.
EDIT: I found a way, without having to install a new version of python:
