Deleting MACOSX_DEPLOYMENT_TARGET enabled me to run the builds.  I  
notice my laptop does not have that defined at all.

The problem machine is a clean install so there were no older pythons  
installed.

I had rarely set the PATH after installing the main MacPython package  
it would always use the new version.  Of course, if that was working  
due to a link, it would certainly explain the behavior I encountered.
