I just ported the latest GLORP (0.2.14) to Squeak.  All SUnit tests pass.

The new port was done slower and more carefully than my old 0.2.5 port, 
and I have a greater amount of faith in it's integrity.  Furthermore, it 
just uses the VW GLORP code (yes, Squeak can file in VW chunk format 
files), with a Squeak "preload" change set that is loaded before loading 
the VW code, and a Squeak "postload" change set that is loaded after 
loading the VW code.  This keeps the Squeak-specific things nicely 
separated, and should make future enhancements trivial to port (in both 
directions).

The updated port on my web site, at:
