To be honest, I'm not sure if this is your problem, because I'm not  
sure what the above program is supposed to do, but it gives a compile  
error when not using hat too.

ghc      -c  -o foo.o foo.hs
foo.hs:1: The main function `main' is not defined in module `Main'

In general, if you give hat a program that produces a compile error,  
then compiling with hat on will give you a more cryptic one.  I  
wonder if this is a place we can improve error messages by compiling  
without hat and spewing out that error automatically.
