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.
Ok thanks, I'll try this.
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.
Ok, that makes sense. I had never learned the proper procedure for building extensions, but have had success with going into e.g. contrib/pgcrypto and typing make to build the pgcrypto extension. Since things like that have generally worked for me I didn't learn about the proper flags etc.
I'll try some more things and get back to you, thanks for the help.
