Frank,

The error message above looks mighty suspicious to me. Where did that
/usr/local/include/uuid/uuid.h come from? I have a hunch that you may
have a locally installed libuuid package that is providing a header
file that conflicts with a /usr/include/sys/uuid.h that came with your
base FreeBSD distribution.

I'm pretty sure that libuuid is entitled to some sort of Guiness world record
for greatest number of stupid preventable bugs for a single small system
library. The proliferation of include/uuid/uuid.h versus include/sys/uuid.h
mismatches is a big part of it, but read our very own Mantis tale of woe for
further entertainment:
