$ cabal-install foo You don't have permission to install packages globally (for all users). Either: run cabal-install as root, or add the --user flag to install packages for the current user only.
cabal-install could drop its permissions for the non-install steps, perhaps. Replace "as root" with "as administrator" for Windows.
Alternatively, cabal-install -rsudo foo or cabal-install -rootcmd=sudo foo (as a user) could call "sudo whatever" when it needs to do something as root. This would probably mean re-executing itself (or a separate binary) with an --I've-built-it-just-install-it-from=/tmp/... flag. This is what various Debian tools do, although it's slightly nicer in those cases as they are just calling a couple of shell commands. Thanks Ian
