 I haven't spent much time with 10.7, although I do have it installed and
 could go there (once about 36 hours of Jeremy's compiler updates finish
 building on 10.6!)

 The point is we don't write Portfiles to run only on the buildbot.

 'clang' means the system clang. It's either used or not. If not, the next
 compiler in the fallback list is used. That is macports-clang-3.4 because
 clang 3.5+ requires libc++.
