Could you try a previous version of matplotlib (look in http://boxen.math.washington.edu/home/release/, e.g. http://boxen.math.washington.edu/home/release/sage-5.9/sage-5.9/spkg/standard/matplotlib-1.1.0.spkg)?
Hopefully the problem is just that matplotlib from some version after 1.1.0 now autodetects libpng and wants to use it. FYI the standard solution we use is to patch packages doing so to look for png12 rather than png because we don't install libpng.dylib on Mac OS X. The reason for that is that otherwise we get trouble with the Mac OS X system-wide libpng (and because Sage messes with LD_LIBRARY_PATH, or its equivalent on Mac OS X). -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
