matplotlib-devel Mailing List for matplotlib

Thanks for the report. This issue was fixed some time ago on the 
maintenance branch, but we have not been very good at getting 
maintenance releases out lately. Hopefully one will drop shortly.

Hi,
I will be on vacation with limited email from July 14 to August 7, 2011.
Bonjour,
Je serai en conge du 14 juillet jusqu'au 7 aout, 2011.

Hi All,
Apparently, some time ago, libpng made the png_info structure opaque. OSX has a newer version on libpng, so matplotlib would not compile. Attached is the _png.cpp that fixes this issue, I changed it to use the new libpng access routines. 
This issue will certainly come up on any platform with newer libpng versions.
