[Haskell-beginners] Broken packages after upgrading to Ubuntu 13.04

[Johannes Engels]

Hello, using the OS-specific Haskell packages of the Ubuntu distribution,
I have some cabal packages installed in addition, e.g. hmatrix etc.
After an upgrade to Ubuntu 13.04 most of these cabal packages are broken
because some dependencies do not exist anymore or have been upgraded also,
respectively. With ghc-pkg check I get messages like

There are problems in package hmatrix-0.14.0.1:
   dependency "array-0.4.0.0-0b32f6f98c0297dbb0e5cfc0087bd1f0" doesn't exist
   dependency "base-4.5.0.0-c8e7184681d410015e93df85fc49e9dd" doesn't exist
....

Actually now array-0.4.0.1 is installed etc.
What is the recommended way to repair this? Should I do a --reinstall of
the cabal packages (which should mostly also work with the upgraded
dependencies)? Any hint would be welcome!
Best regards
Johannes Engels
