Comment (by jonesc@…):

 Hi,

 Build géant 4.10.0 on OSX 10.9, with the blacklist as currently in the
 port

 {{{
 compiler.blacklist  {clang > 503} macports-clang-3.4 macports-clang-3.5
 }}}

 The build ends up resorting to the compiler /opt/local/bin/llvm-g++-4.2,
 which immediately struck me as probably not a great choice, and ultimately
 fails with

 {{{

 }}}

 If I simply comment out the blacklist, and try again, the build proceeds
 and finishes just fine.

 So it appears, at least for OSX10.9, and geant4.10.0, the blacklist is too
 restrictive, and is preventing use of the default clang compiler (which is
 always the best one to use, if it works, I think), which works fine. I
 haven't tested any other geant4 versions though, so perhaps others have
 problems. If they do, then that shouldn't prevent the use of the system
 clang with 10.0, and the blacklist should then be version specific...
