True, for this to work boost should be compiled with libc++ too. Btw, shouldn't
everything work fine when everything is built with gcc5. Like our llvm package
is built with clang ( which is compiled with gcc5 in stage1 ) and it seems to
work fine.

I thought only problem would happen when mixing gcc4 and gcc5 together.
