I have not solved the problem, but I have determined the cause, and this is not the right forum.
Apparently the Libpq that psql is using was compiled from source an was libpq.so.5.1, while DBD::Pg 1.77 was compiled against the Ubuntu-supplie libpq.so.4.1. After doing reasearch it looks like there may be issues with the Ubuntu-shipped library. No need to worry about this. Best Wishes, Chris Travers
