Can't install matplotlib on OS X with PIP

Hi Sameer,

If you are using the default (system) Python, I found that the only extra dependency you need to install is pkg-config. I used homebrew for this ( and “brew install pkg-config”). Alternatively, you can install it directly from the source obtained at Be sure to get the 0.25 release at, as 0.26 has an unnecessary and expensive dependence on glib. To install, unpack and follow the instructions from the homebrew formula:

(mkdir -p /usr/local if needed)

./configure --disable-debug --with-pc-path=/usr/local/lib/pkgconfig:/usr/lib/pkgconfig:/usr/X11/lib/pkgconfig

make install

Don’t worry about the libpng problem - it is fixed in matplotlib 1.1.0, which is available on PyPI. I can’t vouch for pip, but “sudo easy_install matplotlib” did it for me.

Regards and please let me know how it went!
