[Haskell] how to use GHC's prof tools

I developed a program based on wxHaskell but it has serious performance
problem. So I tried to compile the program using "-prof" in GHC. 

If I use "ghc --make -fglasgow-exts -package wx -prof Main.lhs", it
always reports that it cannot find modules defined in wxHaskell like
WXCore. However, if I compile it without the "-prof" option, it works
well and can generate "a.out".

Anyone can give any help?

Thank you,
