 I do not recommend adding such variants. We don't typically do that.

 Replying to [comment:2 macsforever2000@…]:
 > That's why lots of other ports use +gccXY variants.

 I know of no other ports that issue a message such as the one gnuradio
 issued. The reason why most of the ports that have gccXY variants have
 them is because they require a fortran compiler; that's not the reason
 here.


 What is the consequence of VOLK not using the CPU to its fullest
 potential? If the consequences are bad, then consider adding
 "compiler.blacklist clang macports-clang-2.9 macports-clang-3.0 macports-
 clang-3.1 macports-clang-3.2 macports-clang-3.3" until such a time as they
 support clang properly; then MacPorts will build with llvm-gcc. If that
 too will not do, then add "llvm-gcc-4.2 macports-llvm-gcc-4.2" to
 compiler.blacklist; then MacPorts will use apple-gcc instead. Either way,
 add the block that jeremyhu has been adding to lots of ports lately to
 also add the proper compiler dependency, until such a time as #32542 is
 resolved.
