Traceback (and patch) attached, but that's only because I'm stubborn. The
real solution is to package an upstream snapshot.
Upstream is not dead, they just haven't made a release in a while. Plus (as
Oz is finding out) the version in Debian has been disowned by upstream and
probably shouldn't be in another stable release. Very few changes seem
required to update too; just looks like you need to drop 'g2c' from
libraries_list in setup.py.
