yeah sorry i completely missed the title, yeah I tried using the repo's from backtrack 4 which are floating around somwhere have you tried this [I know its for ubuntu but I think it may work]:
I have linux mint too, can you not just google the tools and install them regularly?
I've got metasploit/dradis/SET installed on mint and it's a ballache to config some other tools without creating a exact replica of the bt directories.
