If you recompiled cleanly (ie removed the build subdir) with
VERBOSE=True as instructed, you should be getting tons and tons of
output whenever you run a script (eg can you run simple_plot.py?). If
you are not getting the output, you are probably not running the
matplotlib you think you are. If you do get the output, post it along
with the script and the command line. Also, try running with
different backends, eg, PS, Agg. DO both segfault?
