Title: matplotlib HEAD

Formula for HEAD of matplotlib, a python module. matplotlib currently is not compilable on Lion without libpng 1.2, (and is virtually impossible to install into homebrew's python without compiling yourself) thus I have submitted a libpng 1.2 to homebrew-dupes, and `depend_on` it in this formula.

I'm not 100% on how to manage dependencies that are cross-tap as I have here, I'm sure there must be a better way than blithely assuming that the user will have homebrew-dupes tapped.
