It sounds to me like your life would be a lot easier if you knew about
cabal-install's root-cmd configuration parameter! Open your
.cabal/config file and uncomment and set:
Now cabal-install will take up root permissions when and only when necessary :)
I only found this out after asking #haskell about similar problems.
Perhaps it should be more prominent somehow.
