Comment (by dgelessus):

 Regarding the edit I just made:

 > The configure script of icu tries to call clang-3.4 with the option
 -stdlib=macports-libstdc++, even though icu will be built against libc++
 (via the clang_dependency 1.0 portgroup).

 I think I got that wrong. According to the code in
 clang_dependency-1.0.tcl, the portgroup doesn't change anything about the
 C++ stdlib, it just blacklists some clang versions. So the C++ stdlib used
 by icu would be libstdc++, which clang-3.7 can't compile against. This
 might explain my previous problems with building cmake...
