urlopen error unknown url type: https

After trying to log in with CAS, this error is spat out, and the TracCAS plugin is unloaded:

You need to compile Python (and therefore the socket module) with SSL support.

I just figured that out myself after writing a test case!

The MacPorts versions of Python don't include the SSL libraries by default. If you're using Trac in python25 from MacPorts, you'll also need "py25-socket-ssl" installed for this plugin to work (or py-openssl for python24).
