Yes, that's painful.

Ahh, cool...I'm not the same being bitten too often with it...

Vesa> There's a simple solution to all these problems: for packages

As I mentioned on #archlinux yesterday - there is not 'uninstall' option
for cabal-install.

Vesa> This has worked for me very well, and I'm not sure if I see why we

I agree there is no need for having all the packages, but, thanks to
Don, it's very easy to get 'em all via cabal2arch.

Vesa> Of course also we would have some higher profile stuff in extra
Vesa> (like darcs) and community (like xmonad).

It would be nice to have GUI lib(s) like gtk2hs as well considering
other languages (Perl, Python)
