Errors are similar in clang and gcc:

configure should be generating the correct flags. I see that you're building Proxygen, is it possible that it isn't generating folly-config.h correctly?

[rayrapetyan]

I've tried to build master and tags/0.57 in FreeBSD 10.3 - TLDR seems clang compatibility is broken due to GCC-only patches and checks in the folly code and GCC support in turn is broken in FreeBSD (got errors like 'to_string' is not a member of 'std' etc). So things are much worse now.
