AFAICS arc4random is only referenced in the "BSD" code paths, so you must have tried to specify --with-uuid=bsd. It's not too surprising that that didn't work. As per the docs, your other alternatives are to use the OSSP library or the e2fsprogs library. Or you could just not build uuid-ossp; it's fairly vestigial these days, now that we offer gen_random_uuid() in core. regards, tom lane
