I wonder of we have a(n internal) dependency problem here?     -------^^

Obviously xz is "to be installed", but the distfile(s) of llvm-3.5
depend on xz. `use_xz yes` is correctly, well, used.

llvm-3.5 is installed because of cctools and ld64-latest. I don't get
the ordering, though. xz could potentially be installed before llvm-3.5.
But maybe the "dependencies to be installed" list does not have any
ordering. In any case -- I can't tell why xz iz not installed before
llvm-3.5 currently.
