libpng version incompatibility in fresh installation of IPython

Question

I used this guide to install the \"scientific stack\" for Python (OSX 10.9.2, brewed Python 2.7.6, IPython 2.0, matplotlib 1.3.1, libpng 1.6.10). Everything was looking good

Answer 1

For the sake of documentation (following on from above comments):

Remove X11

launchctl unload /Library/LaunchAgents/org.macosforge.xquartz.startx.plist
sudo launchctl unload /Library/LaunchDaemons/org.macosforge.xquartz.privileged_startx.plist
sudo rm -rf /opt/X11* /Library/Launch*/org.macosforge.xquartz.* /Applications/Utilities/XQuartz.app /etc/*paths.d/*XQuartz
sudo pkgutil --forget org.macosforge.xquartz.pkg

Then,

if you have matplotlib / python installed, run the following as appropriate:

pip uninstall matplotlib
pip uninstall ipython

Then,

pip install matplotlib
pip install ipython

If necessary, XQuartz can be re-installed from https://www.macupdate.com/app/mac/26593/xquartz.

[Note: This does re-add the /opt/X11/include/libpng15/png.h etc files, but ipython worked fine afterwards.]
