The Ghana problem is still there in the latest SVN. I found them in Gujarat in my current Bactrian game, and they also controlled Byzantion and scored 5000+.
Bactria is fun, by the way. I've noticed an error in their UHV text, though: the third goal says 5000 gold IN 40 AD, but it checks once I've acquired it, so it should say BY. I did it easily (with a great merchant pushing me to 5600 gold) by roughly 30 BC, so maybe you can shift the deadline a little.
Also, there seems to be an oversight in Dacia's adjective, as I was asked to take control of the "Dacia civilization".
