[Haskell-beginners] Haskell exectuable size

Hey, I have written a small wxHaskell application. Since wxWidgets seems to be required to be linked dynamicly, I have to add the wxWidgets dlls. Those make a total of about 25MB, wow. Now the compiled exe (compiled with ghc -O2) has size 15MB. In total I am at about 50Mb, which is just to much. Why is the exe so big? Has anyone a suggestion on how to reduce the total size? Thanks!
