I installed atk, gtk2, pango, and cairo from macports. Then I
installed pygobject-2.16.0, pycairo-1.8.2, and pygtk-2.12.1 from the
sources.
All the installations seemed smooth.
However, when I import pylab using GTKAgg as a backend, ipython tells
me that there is not pygtk (see below for the whole error message).
Any insight?
