Hello,
I am trying to build matplotlib from source on CentOS. I have installed all the dependencies, including numpy, freetype, libpng, etc. I also have both the C and C++ compiler (gcc and cgg-c++) installed in /usr/lib/. However when running python setup.py install I get the following error message:
pymods [‘pylab’]
packages [‘matplotlib’, ‘matplotlib.backends’, ‘matplotlib.backends.qt4_editor’, ‘matplotlib.projections’, ‘matplotlib.testing’, ‘matplotlib.testing.jpl_units’, ‘matplotlib.tests’, ‘mpl_toolkits’, ‘mpl_toolkits.mplot3d’, ‘mpl_toolkits.axes_grid’, ‘mpl_toolkits.axes_grid1’, ‘mpl_toolkits.axisartist’, ‘matplotlib.sphinxext’, ‘matplotlib.tri’, ‘matplotlib.delaunay’, ‘pytz’, ‘dateutil’, ‘dateutil.zoneinfo’]

I have scoured the web with no solution. Please HELP!

The error indicates that it can’t find libz, which is extremely odd because if you didnt have it, then most everything else would never work. Which centos are you using? How did you install your dependencies?
