Resolving dependencies...

haskell-gi-base-0.20.5, haskell-gi-base-0.19, haskell-gi-base-0.16 (has the
same characteristics that caused the previous version to fail: excluded by
constraint '>=0.24.0 && <0.25' from 'gi-gtk-hs')
[__1] fail (backjumping, conflict set: gi-gtk-hs, haskell-gi-base)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: gi-gtk-hs, haskell-gi-base
