I'm new to Backtrack and have just installed permanently onto a USB, my install worked fine and Backtrack seems to be working fine. However, when i tried to run Autopsy i am getting the error:

conf.pl did not return a true value at /pentest/forensics/autopsy/lib//Main.pm line 62.
Compilation failed in require at ./autopsy line 56.
BEGIN failed--compilation aborted at ./autopsy line 56.

Can anyone help me with this error code as i need to access Autopsy for uni work.

Thanks for any help anyone can give
