Re: How to compile git-annex?

parsec-3.1.9 (reinstall) changes: mtl-2.1.3.1 -> 2.2.1
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.)

I clean up all Haskell related things in my home directory.

cabal update
cabal install cabal-install
Then I try to install git-annex again, which shows me the following.
What I should do next?
~$ cabal install git-annex

Use --force-reinstalls if you want to install anyway.

Why cabal install print so many irrelevant messages? Is it better to
