GHC.Prim problem

[Ben Sinclair]

Hello, I've had a problem with GHC.Prim when compiling the darcs HEAD
lately. When I compile it in the normal way with no special options

> sh boot && ./configure && make && make install

it compiles correctly, but if I attempt to compile

> module Main where
> 
> import GHC.Prim
> 
> main :: IO ()
> main = return ()

then I get this output:

> $ ghc --make Main.hs -fglasgow-exts -v

Is there anything I should be doing to make this work? Thanks for any
advice,
