Created attachment 194917 [details] patch to enable all options on 10.x After r473980[1], devel/llvm60 is ready for OpenMP on all FreeBSD versions, except for 10.x. I tried the attached patch to remove the blocking line for 10.x, and 10.x seems to build functional OpenMP on both, amd64 and i386. [1] https://svnweb.freebsd.org/ports?view=revision&revision=473980
