 I must have made an error when I searched in vi for vercmp. Doing it again
 and more controlled I found the second occurrence and now

 {{{
   clang-4.0 @4.0.0_0+analyzer+libstdcxx (active)
   llvm-4.0 @4.0.0_0 (active)
 }}}

 are built. Building llvm-4.0 with polly is certainly not recommended
 because the ppl port is installed and also used by other ports.

 Thank you, Ken!
