Thanks for your replies!

I tried just adding -x, which gives the same result as -c.

This may seem kind of trivial, but I'm having a little trouble installing modules. I used the PPM app to get the stuff I needed (such as Tk itself), but it installs them for the user, and pp seems to ignore those, so I got it to work with use lib instead, but now if I update PAR, I assume it will put that in the wrong place too... it's a bit of a mess.

I think it should be possible to get PPM to install it in the right place, but I can't work out how to do it. I tried changing a bunch of permissions, but that didn't seem to do anything.
