The FreeBSD port just installs the zipped .egg file for M2Crypto and there
is no option to make or install an unzipped version.  Unfortunately, the
zipped version gets unpacked, per-user when it is first used and the
directory it is unpacked to is not always writable.  To avoid unsightly
"permission denied" failures, we run a post-package-install phase to
manually unpack the .egg in the python site-library directory.  This is
wicked ugly and I really should be flogged for doing this...

We will deal with Resolve versioning issues later.
