*If* you ever have to install something globally with cabal, note that
you should use

  cabal install --global --root-cmd=sudo

and NOT 'sudo cabal install --global'.  This is so that cabal will
only take root privileges for the actual copying/installation, and not
pollute your package cache, etc. with files owned by root.

*But* as Norbert says (and I strongly agree), it is not recommended to
use --global with cabal, unless you know what you are doing and
why.
