Yes, I did, sorry.

That produces

  cabal: The following packages are likely to be broken by the reinstalls:
  process-1.1.0.2
  haskell98-2.0.0.2
  ghc-7.6.3
  Cabal-1.16.0
  bin-package-db-0.0.0.0
  directory-1.2.0.1
  hpc-0.6.0.0
  Use --force-reinstalls if you want to install anyway.

cabal doesn't have a sandbox command.  I guess that means it's too old.
Sorry I don't know much about this stuff.

I'll try reverting to the old .cabal tomorrow.  Thanks.
