[Haskell-beginners] [Fwd: Re: [Hat] How to use Control.Monad.State?]

[Larry Evans]

Since the hat mailing list seems a bit unresponsive,
(or I seem to be impatient),
I'm forwarding the attached post here.
I've also attached the Makefile that produced the
error message shown in the attachment.

When the Makefile target is run, it works.
However, with target=hat, It produces the
error shown in the forwarded msg:

Hat/tickSimple.hs:4:0:
   Bad interface file: 
/usr/lib/haskell-packages/ghc6/lib/hat-2.05/ghc-6.8.2/Hat/Prelude.hi
       Something is amiss; requested module  main:Prelude differs from 
name found in the interface file hat-2.5:Hat.Prelude

Please, how should the Makefile be modified to
avoid this error?

-Hopefully,
Larry
