GHC includes “transformers”, which is what most packages use, but
“ghc-mtl” includes a different version (it has the same version number,
so it is hard to see from the warnings).

Actually, Ricardo already pushed a fix that should clear up the
“ghc-mtl” problem.  My patch just applies the same idea to all the other
packages that have the same problem (originally it included “ghc-mtl”,
but Ricardo beat me to it).
