 clang uses llvm's distfile, so it would be best to share llvm's
 dist_subdir so that users don't have to download the llvm distfile twice
 -- once for the llvm port and once for the clang port. This would also
 help our mirror servers not need to mirror the llvm distfile twice (in the
 future; the damage is already done for version 2.9).

 This would be accomplished by adding this line to the clang portfile:

 {{{
 dist_subdir llvm
 }}}

 You can either do it now (which would cause the distfiles mirrors to
 download and mirror a second copy of the clang 2.9 distfile), or you can
 wait until you update the portfiles to the next version of llvm / clang.
