(In reply to Mikhail Teterin from comment #2)
That would be bug 210337. USES=compiler:openmp cannot use Clang in base on
FreeBSD 10.* because -fopenmp is ignored there, cannot use Clang from
devel/llvm60 on FreeBSD 10.* because OPENMP is unconditionally disabled in the
port, cannot use Clang on non-x86 where LLVM openmp isn't supported (on
FreeBSD) and Clang cannot use libgomp (from lang/gcc*). And lang/gcc* is often
required by USES=fortran consumers directly or via libgcc_s pollution.
