oh I didn't notice it was off-list. sorry.
Anyway, on OSX and I think Linux, Squeak/Pharo is using uuid_generate(3)/libuuid
or uuidgen on systems like Free/NetBSD

Note that the Squeak folk detected problems especially on Ubuntu
---causing segfaults when trying uuid stuff (which happens all the time with
monticello)---
that date back to 2010. I remember folks at ESUG being bitten by that
problem.
See discussion here:
http://forum.world.st/Fix-for-UUID-library-crashes-td3308033.html
http://bugs.squeak.org/view.php?id=7358

The tricky solution there was to catch a possible segfault
and continue with image-side in this case:
(diff) http://squeakvm.org/cgi-bin/viewvc.cgi/squeak/trunk/platforms/unix/plugins/UUIDPlugin/sqUnixUUID.c?r1=2356&r2=2362
(code) http://squeakvm.org/cgi-bin/viewvc.cgi/squeak/trunk/platforms/unix/plugins/UUIDPlugin/sqUnixUUID.c?revision=2602&view=markup
