Comment(by guest):

 There are a few options, one of which might get you unstuck:

 You can reinstall a package:
 {{{
 cabal install --reinstall haskell-src-exts-1.10.2
 }}}

 Or you could use `ghc-pkg unregister` instead of `cabal uninstall ...`

 For a long term solution, I would recommend using `cabal-dev` to install
 packages in their own sandboxes where their dependencies won't affect the
 build of other things on your machine.
