I am guessing that the problem is that we're looking for the uuid.h
that comes with the OSSP package, and you're uuid.h is something else.
You might want to see if there's anything helpful in config.log.
Weirdly, there don't seem to be any UUID-related changes to
configure.in between 9.1 and 9.2beta1, so I'm not quite sure why
you're seeing different behavior.

Hi Robert,

I did some experimenting.
I have uuid.h from the OSSP uuid page, version 1.6.2 installed.
Removed /usr/local/include/uuid.h
rebuilt and re-installed the package.
Same error - but also in 9.1.

So I copied /usr/include/uuid/uuid.h to /usr/local/include/uuid.h and the error went away:
checking for uuid_export in -lossp-uuid... no
checking for uuid_export in -luuid... yes
...
checking uuid.h usability... yes
checking uuid.h presence... yes
checking for uuid.h... yes

go figure ... ;).

best regards,
chris
