I do this at work where I share the same home dir between several 
different machines, and my .cabal/config contains

install-dirs user
   prefix: /home/simonmar/.cabal
   bindir: $prefix/bin/$arch-$os
   -- libdir: $prefix/lib
   libsubdir: $pkgid/$compiler/$arch-$os
   -- libexecdir: $prefix/libexec
   -- datadir: $prefix/share
   -- datasubdir: $pkgid
   -- docdir: $datadir/doc/$pkgid
   -- htmldir: $docdir/html
   -- haddockdir: $htmldir


Hope this helps.

Cheers,
