What does pkg-config libpng --modversion --libs --cflags
give? The pkg-config error may actually be a red herring, since matplotlib will look in /usr/local even if pkg-config fails, and it obviously found the headers or it wouldn't have gotten to the linking stage. As the author of the pkg-config support I would like to rule that out as the problem though. I think it's more likely that the libpng isn't being built correctly to match the kind of binary matplotlib is building. I'm afraid that's where I hit the end of my knowledge as a non-Mac user, but I'm sure another Mac developer will chime in.
