Yes that's openshadinglanguage failing.

That line with the error indicates that it is using llvm34 - osl
currently doesn't build with llvm34 and should be setup to use llvm33.

In /usr/ports/graphics/openshadinglanguage/Makefile there are three
places that have llvm-config33 - check that they are 33 and not 34
