Try to compile 7.0 or 7.1, those versions will probably still support the 
6.4 wire protocol. I am sure someone with more historical knowledge (or 
reading the release notes back to 6.4) can exactly tell you the latest 
version compatible with 6.4.

It was already said, but please -- upgrade. Any version before 7.2 is going 
to eat your data after a certain amount of transactions.
