This patch shows how I propose dealing with Cabal's inability to build dynamically linked installable executables.
In short:
- Create links to all DSOs from /usr/lib/ghc-7.6.3/shared.
- Rewrite rpath of executables to only contain
/usr/lib/ghc-7.6.3/shared.
Any comments? (Besides the hard coded ghc version in the path ;-)

Subject: [PATCH] Deal with Cabal's deficiencies in linking dynamically.
With this change PKGBUILDs of libs create symbolic links to the DSO at
/usr/lib/ghc-7.6.3/shared. They also modify the rpath of all executables,
replacing the one put in place by Cabal with one of a single entry:
/usr/lib/ghc-7.6.3/shared.

There's a big difference between making something easy to use and
making it productive.
