py27-matplotlib: AttributeError: When using gi.repository you must not import static modules like "gobject".

I'm getting a weird error from matplotlib. This script was a working scrip that I have used many times, and last week after updating all my port definitions, it broke and gave me this error. The trace is as follows:

I am using a MacBook Pro running OS X 10.9.5. My active python port is python27 @2.7.8_2+universal and this script was written for using graph-tool (which is a python package for network visualization). It depends on boost, so I am using boost @1.56.0_1+no_single+no_static+python27+universal and my graph-tool port (if that's relevant) is py27-graph-tool @2.2.35_0. Please help!
