'cabal install AD' fails when installing semigroupoids about ad

[glguy]

ad builds against semigroupoids-5.0.0.2 using all the current versions of packages. Could you provide a list of all the versions of packages you're building against via ghc-pkg list ?

[fouronnes]

Sure. Could that mean one of those is out of date?

[glguy]

My guess is that you've got bifunctors compiled against a different version of the tagged package than you're compiling ad with.

Closing this. We've rejiggered a bunch of stuff around bifunctors and tagged since this. If someone else gets this issue, please feel free to re-open it.
