I have been trying to install Listen 0.6.3 all day. It came up with the error that PyGTK was not installed, so I installed it, I had a few problems, but they got ironed out, and as far as I can tell it was installed, but going back to try to install Listen it still says that it isn't installed.

Is there any way to find out if it is definately installed or not?

Sorry if this is a daft question, but I installed linux for the first time yesterday.
