[Python-3000] 3.0 alpha builds break on FreeBSD.

That's not what the buildbot says:

A specific error message, literally copied from the configure output,
would be helpful (assuming there really is an error message from
configure, rather than configure complaining by some other means
than an error message). Along with that, the snippet from config.log
immediately preceding that error message might also be needed.
