Cabal sandboxes as it stands right now are not portable at all, global paths are only the beginning. For example you cannot use a sandbox created on another machine by default, unless you have *exactly* the same environment (e.g. use the same build of the Haskell Platform).

I wrote a small tool called SandFix that we use internally at my workplace that fixes global paths and tries to fix all package dependencies as well so you can reuse a sandbox created on another machine. I uploaded it now to github: https://github.com/exFalso/sandfix. It works quite well for us. Note that it assumes a ghc environment.

I would also prefer relative paths for sandboxes.

This project seems to do what you want (I didn't test it):

Although I think it would be better to have relative file paths in cabal.sandbox.config...

There is no way to move the project to a different place without recreating the whole sandbox.

It would be nice if there were a tool to do this. It should not be difficult to programmatically adjust those paths and the ones in the ghc package directory, and reindex the latter.
