 Replying to [comment:4 bgamari]:

 GHCi's dependencies around GHC 7.8 has been dealt with? Otherwise this
 will just throw us back to square one with the bugs/issues we had pre-7.8.

 comment:ticket:8919:17 gives a summary of the issues involved which
 eventually lead to 4caadb7cbee5c176abb99df25c4cc1657ae57f40; and you can
 find some potential approaches to addressing the issue mentioned in the
 surrounding discussion.

 Note however, that `lib:Cabal` has also slowly been acquiring more
 dependencies, such as `lib:mtl`, `lib:text` or `lib:parsec` (and I've
 recently realised that the option of not bundling `lib:Cabal` with GHC is
 not feasible anymore for reasons related to catch-22s in the bootstrapping
 process).
