Well I am not sure if this is really a bug. There may have been some changes do to recent updates of fasttrack.
Just install psycho and you will be good to go, I believe you can do so right from the FT directory, look for a install or setup script. I don't remember the name right off hand, and don't have access to my BT machine. If you get stuck just post back and I will look into it again.
EDIT: In /pentest/exploits/fasttrack/ run # ./setup.py and it will take care of things for you.
