Ok, it's a bigger job than I realized!

Do you think it's helpful then to run these builds with different Python
versions enforced?  I thought that getting the version ranges in the
USE_PYTHON variable tightened up might help reduce the number of folks
who run into build problems.  I would like to do the same thing with
Perl, GCC, and others.
