I think the key question is what version of the ossp code are you using?
We've had lots of reports of *that* failing to build on modern platforms,
but since development on it stopped years ago, it's not exactly a moving
target. I'm surprised to hear of a case where you can still build the
ossp code but our code then fails. Also, when was "used to"?

On Mac, the recommended thing is to forget about the ossp code and
use "configure --with-uuid=e2fs". Sorry if that wasn't clear enough.

Reading over your post again, it sounds like you're trying to force-build
contrib/uuid-ossp without having used any of the configure options that
are supposed to enable it. I'm not sure that would ever have worked very
reliably.
