In tune emulators/open-vm-tools-nox11 fails. This seems related to changes for llvm and accompanying libraries. In this case libiconv.
>How-To-Repeat:
Compile devel/glibc20 on FreeBSD 10-STABLE or 11-CURRENT. On both systems compilation fails if done with the default compiler from the llvm-toolchain.
>Fix:
Unknown. If switching to gnu libiconv other parts of the system won't compile.
