[chimera-dev] BioPython on Mac OS X

[Mateusz Dobrychłop]

Dear Chimera Team,

I'm currently trying to install BioPython using Chimera's Python copy on
Mac OS X.

Thanks to the Chimera Programming FAQ, I've already managed to install
BioPython succesfully on Ubuntu, but on Mac OS X I get the following error:

Is there anything I can do to solve this problem?
