[Haskell-cafe] Cabal message problem.

[Magicloud Magiclouds]

Hi,
  I see this kind of information a lot when I using cabal to install
package. Or sometimes same packages both exist in global and user
space, which is a "shadowed by" message.
  How to resolve that? Thanks.

Resolving dependencies...
<command line>: cannot satisfy -package Cabal-1.10.0.0:
    Cabal-1.10.0.0-9ac678c7f1e4f8dd31bac0e19f600698 is unusable due to
missing or recursive dependencies:
      process-1.0.1.4-24e3819e5c17aaf49bfec6a0ab739420
    (use -v for more information)
