Should be fixed in https://github.com/gentoo-haskell/gentoo-haskell/commit/04cb27bf8124a96747d81cab933573a74d8290cd (In reply to Jack Todaro from comment #1) > Should be fixed in > https://github.com/gentoo-haskell/gentoo-haskell/commit/ > 04cb27bf8124a96747d81cab933573a74d8290cd I think that's a workaround. Emerge should figure out that it shouldn't upgrade pantry because stack requires <dev-haskell/pantry-0.5.

Depending on the state of you dependency graph, you may need to use a larger emerge --backtrack argument in order for backtracking to solve the problem. You can use the make.conf EMERGE_DEFAULT_OPTS variable to increase you default --backtrack setting. A large enough number for --backtrack should be enough |
