[BioPython] mxTextTools for new Macs

[dag23 at duke.edu]

Hi List of helpful people,

     I've a new MacBookPro and in attempting to install mxTools, I've hit major
snags.  While this isn't a BioPython issue per se, it might impact those trying
to install the BioPython required files on the new architecture.  Has anyone had
similar issues?

Cheers,

David
