Alan Knight had a working VA port of Glorp and StoreGlorp at ESUG 2004 in Kothen, which he demoed. AFAIK, he did not maintain this to more recent versions. However, I ported a later state of Glorp to VA in mid-2005, and then did a VW3/Envy port, which of course is the same for a high proportion of the code.
Some of this is in my home office which I will next be in this Friday / weekend. AFAICR, the little-tested VA port was of Glorp 0.3.174, StoreGlorp 2.2.52 with GlorpTest and StoreGlorpTest of the same vintage. The well-tested VW3/Envy port was at least up to Glorp 0.3.178 and and StoreGlorp 2.2.53 and may be some versions newer (but not 0.4.anything).
By coincidence, I have just begun to look at Glorp in VA again. I will contact you later this week with more information.
