I had the exact same issue. Installing ghc-static fixed it.

You probably need to tell ghc to use shared libraries via the -dynamic flag, e.g.

$ ghc --make -dynamic path/to/file.hs

Doing this means you do not need to install the ghc-static package.

Try to tell ghc to build dynamically linked object files and executables, e.g., by

cabal install --dependencies-only --ghc-option=-dynamic
