Negative. Using or requiring APR first (use APR; use APR::UUID;) does not fix the problem. Not using APR at all isn't a problem here, since the command line version at the end of my post works.

Second, it works as-is on every platform except for OpenBSD. I think that's the marker of something strange going on here.

In fact, just 'use APR;' in the Makefile.PL above causes the same problem.

Update: I just got a copy of the mp2.0.2 source on the server in question. the uuid tests pass fine:

test:~/mod_perl-2.0.2/t$ perl -T -Ilib apr-ext/uuid.t
