Hi,

json does not emerge for me using stable ghc and testing json.

The haskell folks say that the issue is ghc 6.12, so I’m now upgrading ghc to 7.4.

I just wanted to ask “what’s blocking ghc 7.x from being called stable”, but well: https://bugs.gentoo.org/buglist.cgi?quicksearch=ghc&list_id=1365854

I hope ghc 7.4.1-r1 will make everything work again. It’s a bit sad, though, because I try to keep most of my system in stable.

Soon (starting in about 1 week) we will push ghc-7.4.2 to portage using EAPI=5 along with lots of haskell pkg bumps using EAPI=5.

After updates it takes at least 30 days for a pkg to be stabilized. It will be the new ghc versions and package that we will soon push using EAPI=5 that we will want to stabilize. Since we wish to use EAPI=5 for new ghc versions and haskell packages I am not sure how long it will take to stabilize them.

EAPI=5 is really neat for haskell packages, as portage knows to rebuild the immediate reverse dependencies when packages are updated. The rest (non-immediate) reverse dependencies are rebuilt with haskell-updater.

We are using the EAPI=5 subslot feature to help with ghc version upgrades. This is all being tested now in the gentoo haskell overlay.
