The specific reason I had to include base-4 and syb was due to the error:

    Could not find module `Data.Generics.Instances':
      it is a member of package base-3.0.3.0, which is hidden

While the error message implies base 3 should be used,  "member of
package base-3..", I decided I wanted JHC to compile against base-4
(Perhaps unnecessarily?) and instead added base-4 and syb (Which
contains Data.Generics.Instances).

I recall trying to just use base 3 and using that to compile JHC. I
think (Gee I should of taken notes...) the reason this failed was due
to other missing dependencies. Perhaps Control.Exception dependencies.
And I found it easier to just use base-4 instead.
