Well, it doesn't seem too hard to check for the existence of
${prefix}/bin/python2.* and add a depends_build if there's none. I don't
really see why this would be superior to using /usr/bin/python if any
old 2.x python will do, though.

Personally I'd just use python27 and be done with it, but people always
seem to complain when you do that.
