cabal can not be found by apt-get, neither on MacOSX nor on Ubuntu-Linux 10.10:
---
ubuntu:~$ sudo apt-get install zlib1g-dev cabal emacs ghc6 haskell-mode
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package cabal

Yes, I upgraded and updated apt-get before.

So, it is not that simple.
