How do I add ghc-prim as a dep for ghc?

[Ömer Sinan Ağacan]

I'm trying to add ghc-prim as a dependency to the ghc package. So far I've done
these changes:

    diff --git a/compiler/ghc.cabal.in b/compiler/ghc.cabal.in
    index 01628dcad1..b9c3b3d02b 100644

But I'm getting this error:

    ghc-cabal: Encountered missing dependencies:
    ghc-prim ==0.5.3

Any ideas what else to edit?

Thanks,
