That only applies to the Xcode clang versions, as far as I can tell.

Why? Why would it not be possible to check if macports-clang (or clang-mp)
newer or older than some version is installed, or why would it depend on having
used port select?
Extending range selection to MacPort's clang versions only means that it
becomes possible to use a short-hand notation for something that would
otherwise require listing each versions concerned explicitly. It's not like it
introduces a forbidden feature ...

3.7 also fails to build on a system that does have libc++, or so at least I
have been told. I've never bothered to install clang > 3.4 on my 10.6 system;
gcc-mp-4.8+ worked just fine for me and was a lot faster than even clang 3.4 .
