Comment:
Unfortunately it doesn't really make sense to talk about reinstalling all
dependencies of something. Afterall, that includes base etc which either
you cannot reinstall or do not want to reinstall. So you don't really mean
/all/ dependencies. You mean the broken packages.
Now cabal cannot tell when packages are broken due to missing files, only
due to missing package dependencies. So the solution to your problem is to
unregister the packages that have the missing files. Then `cabal install
-only-dependencies` will do the right thing.
So for example if you removed your ~/.cabal dir, then you can unregister
the same packages by removing the ~/.ghc directory.
Perhaps the proper solution here is for cabal to notice when packages are
broken due to missing files. That will have to wait 'til cabal does better
package management (tracking files for uninstall).
