Comment (by lemzwerg):

 Poking around, I found the following small failing example.
 {{{
 sudo /opt/lilypond/2.19.83/bin/port -N install clang-3.4
 --->  Computing dependencies for clang-3.4
 --->  Dependencies to be installed: libxml2 icu clang-3.7 clang-3.4
 llvm-3.7
 Error: Follow https://guide.macports.org/#project.tickets to report a bug.
 Error: Processing of port clang-3.4 failed
 }}}
 Note how `clang-3.4` appears in the list of dependencies, too.
 Complete (small) log file attached.
