Hi Daniel.
I haven't used rpm based systems very much. So this might not help you
..

Try using ldd on you ghc binary to see all dll dependencies.
Perhaps this gives you some info why the libraries aren't found.

In general you can try using tools like www.rmpseek.com to find missing
packages.
If libraries aren't found running ldconfig might help. This recreates
all symlinks.

But perhaps the most easiest way is trying to make your sidux box using
debian package repositories (don't know wether this messes up your
system) as I think the ghc rpm package was compiled and tested with
them.

You might also try installig ghc from source (you need another ghc
binary install first to bootstrap) You can find documentation about how
to install from source on the ghc site.

If really everythig else fails you can also create a new environment
containing another os (such as debian) eg by using user mode linux.
(Then you need some more disk space)

Do you have any recent ghc running?

Good luck
