The latter, sort of. The error in question..

What happens is that one the dependencies of openimageio was built against the old C++11 std::string ABI (hence the link errors), and needs to be rebuilt. It looks to be "Imf" aka libIlmImf, whatever that is. Try to rebuild it with --oneshot and it should work. If a similar error pops up for a different dependency, repeat. :) -h
