Sorry - I am afraid I installed the combo updater over the existing X11 before I read your email properly, so I don't know what version I had before. > As far as I know there is no standalone X11 2.3.6 updater for Snow Leopard. > You'll have to re-install the security updates that came out after the combo > updater was released if you use it, which is a bit of a pain.

So, to summarize, pip install for matplotlib will fail on bare-bones OSX 10.6 unless you do one of: * Run the combo updater * Install Quartz X11 * Build your own libpng in /usr/local Is that a reasonable list? Is there any way to check for this problem and warn / error at build time with instructions?
