libc++ problem

[Roelof Wobben]

When I try to compile cinnamon-control-center I see this output :
lvm[0]: Installing HTML Clang Tools Documentation
llvm[0]: Installing PS Clang Tools Documentation
install -o root -g wheel -m 444 /usr/ports/lang/clang33/work/llvm-3.3.src/tools/clang/docs/tools/clang.1 /usr/local/man/man1/clang33.1

===> libc++-185324 Doesn't build due to lack of aligned_alloc().
*** [install] Error code 1
Does anyone how to solve this one ?
