Attempting to build any package which depends on the hlibgit2 library causes an error regarding required versions of Cabal:

I don't know enough about the cabal build system to be able to trace down exactly what needs to be changed, but I haven't seen this behaviour from any other package. This happens both when installing from Hackage and when building locally from the latest Git source.

Looks like it's this one: https://github.com/haskell/cabal/issues/5278

However, it also looks like it's fixed at head by removing the custom build type, so we probably just need a hackage release. Meanwhile, I finally learned a bit about newer cabal and discovered that I can work around by cloning the latest locally and putting it in cabal.project packages: /path/to/gitlib/hlibgit2/*.cabal

@jwiegley can you or another maintainer do a hackage release? This should fix it for darwin without the need for manual workarounds. Or if there's a way to give me permission I could do it, as (one of the few?) users I could take over basic new ghc version maintenance.
