 Long title, apologies.

 I would be helpful if we could find an association between Apple clang
 releases and macports-clang-N versions such that blacklisting a given
 version of clang, such as {clang < 800} would automatically also blacklist
 macports-clang-3.8 and below (or whichever version best correlates).
