If you've built pygtk then the target sysroot should have the headers
in, and for me it does:

ross at melchett /data/poky-master/tmp/sysroots/genericx86
$ find . -name pygtk.h
./usr/include/pygtk-2.0/pygtk/pygtk.h

This is probably a problem with python-matplotlib, can you share the
configure and build logs?  It's probably looking in the wrong place.
