Enclosing "*gcc*" and "macports-clang-3.[0-2]" in curly brackets looks strange
to me. The reason "clang < 500" is quoted is so that it will be interpreted as
a single value and parsed by the compilers_blacklist_versions portgroup, but
"*gcc*" is already only a single value so doesn't need to be quoted. The ports
clang29, clang30, clang31 and clang32 no longer exist so there's no need to
blacklist them.
