Link errors when using the GHC API

[Christian Maeder]

The binary distribution

http://www.haskell.org/ghc/dist/6.6/ghc-6.6-i386-unknown-linux.tar.bz2

does not contain libHSghc.*

So I get:

Loading package ghc-6.6 ... ghc-6.6: can't load .so/.DLL for: HSghc
(libHSghc.so: cannot open shared object file: No such file or directory)

C.
