[Haskell-cafe] Why does ghci recompile the module compiled in different OS ?

[Gaius Hammond]

Are you trying to use the .o compiled on BSD on Linux? They are two  
different operating systems. So the Linux ghci isn't using the .o,  
it's using the .hs. Even getting Haskell binaries to run on two  
different versions of Linux can be an adventure...
