Yes, that's completely unrelated to library availability issues. I got

Hi
It's not a great experience now, but hopefully things are moving in

Cabal-install is intended to remove this problem, so that you can say
"i want crypto" and it gets everything that requires.

I was explaining Haskell to a perl/python hacking friend recently and

Perl is a horrible language with fantastic libraries.
Haskell is a fantastic language with horrible libraries.
