mtl is almost certainly installed globally, and installing a private copy is likely to cause all sorts of problems (as indeed cabal told you). Since I see a bunch of yesod dependencies, I suspect you need to throw out your global Platform installation because yesod does not bother with Platform compatibility and in fact breaks it completely. Get a minimal ghc and install Stackage, because that is the only install that yesod will tolerate. (And get used to a world where your choices are either to let yesod determine what you're allowed to install, or use a supposed standard that certain parts of the Haskell world believe they have a mission to destroy.)
