Dear c.l.l. readers:
I am currently looking for something that ought to be done
already by someone (googling for it just revealed nothing
usable - at least not in CL). Oh, btw, this is not any
homework ;-)
I am looking for an example of a UUID generation in any
Common Lisp implementation out there that does *not*
call a library via FFI.
I have the UUID spec at hand but, well, I'm lazy ;-)
Thanks for sharing this bit of code!
Frank
Is this what you need?

Actually, no. But thanks for pointing out. I should have stated more
clearly that I am looking for a CL version.

Here is a time based one I just wrote, not thoroughy tested and will
only work in its current form on LispWorks For Windows.
(It does not support non-volatile storage of
vars to generate UUIDs, though this should not be a real problem,
unless one sets the system clock backwards between Lisp
processes.)
This should give you a place to start.
