You will need to ask cabal to use a different package database (and
your users will need to ask their cabal installations to also use that
database). The simplest way to do this is to simply add "--global" to
the install line; however, this may not work if you don't have root
access.

Hi,
I have been trying to install xmonad (using cabal) for the past week for a group of users and having some issues with it. When I try to install it for myself it works just fine, but I when I try install it for a group of users, it gives me errors that some packages/modules are missing. I used the following cabal command:
cabal install --prefix=$PREFIX --build-log=/tmp/xmonad.log.3 xmonad (where my prefix is /net/tools/xmonad/0.10
I see the installation there, I can run it myself, but when another user goes about it running it from the same installation, it complains that some packages/modules missing. I noticed that my installation creates $HOME/.ghc directory where all the packages are registered. I think therefore, for another user it can't access my $HOME/.ghc and therefore fails. Is there a way to tell cabal installer to register the packages in the $PREFIX area? I am so new to ghc, I tried figuring it out, but I could not. I think if I can register the packages somewhere in the PREFIX (/net/tools/xmonad/0.10) area, then xmonad running for a different user(s) will be able to access the right packages, and that might fix this issue. thanks in advance.
