OS X 10.8's default OpenSSL doesn't have Camellia, so that one causes immediate problems (I'm unsure of Mavericks). For testing this I have a patch I apply to api.py to specify a library_dirs and include_dirs of my brewed 1.0.1e.

Camellia is reliably supported on the most popular Linux distributions, but we're fast approaching GCM, where we'll run into this problem again since Red Hat disables it in their OpenSSL build. CTR was also unsupported prior to 1.0.0, and that's the next mode I intend to commit post-Camellia.
