[BioPython] (fwd) Python module for DNA to amino acid and reversecomplement translation.

[Jeffrey Chang]

This is actually what happens.  It'll load the C extensions if they exist,
but fall back on the pure python version if they don't.  The problem is
that distutils doesn't make a big enough deal if the compile fails, so
that if the installer isn't paying attention, they could be running the
slow version and not know it.
