I think you're just missing a "--user":

$ cabal install --prefix=$HOME --user foo

The prefix can also be set in the $HOME/.cabal/config file.

Syntax? Something like: prefix: /path/to/my/ghc ?

Yes, but using ghc's path would be a really bad idea. Actually there's "user-prefix:" and "global-prefix:" for the prefixes to use when using --user or --global installs.

BTW, In the development version of cabal-install --user is the default and the default user prefix is $HOME/.cabal (though both can be changed in the config file).

Is this newer than 12 hours ago? I tried "cabal install --prefix=/path package" (without --user). That did not seem to work...

Remember, --user is default unless overridden by --global. So if you are trying to install as root that probably will not work since it'll probably have been built against packages that were in your user's package db but are not in your root users package db. We've not concentrated very much on global installs yet for cabal-install. We've been trying to make ordinary user installs "Just Work"tm. There was a bug a couple days ago where the prefix given on the command line was being overridden from the one given in the config file. That's now fixed. The command line overrides the saved config settings. So if it's still not working for you, you'll have to give more details. Details of what command you were using exactly and what the error message was. Duncan
