 LHC (as of September 19) doesn't build with the latest Cabal.

 Simply replacing 'package' with 'sourcePackageId' doesn't work: Cabal
 seems to have changed package dependency handing a bit:

 {{{

 lhc-pkg/Main.hs:520:53:
     No instance for (PackageFixedDeps InstalledPackageInfo)
       arising from a use of `depends' at lhc-pkg/Main.hs:520:53-63
     Possible fix:
       add an instance declaration for
       (PackageFixedDeps InstalledPackageInfo)
     In the second argument of `filter', namely `(depends pkg)'
     In the expression: filter (not . realVersion) (depends pkg)
     In the definition of `unversioned_deps':
         unversioned_deps = filter (not . realVersion) (depends pkg)
