New description:

 valgrind fails to build already at configure time if clang from xcode 425
 is used, complaining about too old compiler:
 {{{
 checking for a supported version of gcc... no (applellvm-4.2)
 configure: error: please use gcc >= 3.0 or clang >= 2.9 or icc >= 13.0
 }}}

 A naive addition to the Portfile that blacklisted /usr/bin/clang++ (and
 llvm-gcc-4.2 just in case) made the build succeed:
 {{{
 PortGroup           compiler_blacklist_versions 1.0
 compiler.blacklist  *gcc* {clang < 500}
 }}}
 but I didn't test macports-clang-3.3, llvm-gcc-4.2 or xcode 5. I'm also
 not sure whether the port needs some special handling about gcc (I don't
 understand what the rest of the portfile does).

 It is also possible that the configure script simply fails to realize that
 clang++ is in fact some flavour of clang 3.2 (based on LLVM 3.2svn) that
 might work if the configure check was fixed.

 I can do more tests if needed.
