problem installing matplotlib

src/_gtkagg.cpp:32: error: `GDK_DRAWABLE' undeclared (first use

Hi Alex, could you provide your platform information, python version
and pygtk version. The latter is obtained by

> pkg-config --modversion pygtk-2.0

The gtk backend requires pygtk 1.99.16 or later, which *may* be the
src of your troubles.

You might also include the gcc commands that are generated in building
gtkagg since I might get some information from the include and library
flags.
