 Default compilers on 10.6 and earlier (gcc-4.2, llvm-gcc-4.2, early clang
 < 3.0) don't support -std=c++0x.

 Possible remedy is to use PortGroup compiler_blacklist_versions to
 blacklist these compilers.

 {{{
 PortGroup           compiler_blacklist_versions 1.0
 ...
 compiler.blacklist  *gcc* {clang < 300}
 }}}

 This will cause the compiler selection to fall back to a more recent
 compiler (MacPorts clang-3.4 in this case).
