[wxhaskell-users] wxhaskell with ghc-6.4.1: "mismatched interface file versions"

[Conal E. <co...@co...>]

I got last night's ghc-6.4.1 winxp build snapshot, hoping ghci &
wxhaskell would now work together.  After doing wxhaskell-register.bat,
and running "ghc -package wx", I get

   Failed to load interface for `Graphics.UI.WXCore':
       Bad interface file:
C:\wxhaskell-0.9.4\lib\imports/Graphics/UI/WXCore.hi
           mismatched interface file versions: expected 6041, found 6040

When I run under emacs, I now get this error (new)

    Loading package wxcore-0.9.4 ... linking ... done.
    Loading package wx-0.9.4 ... linking ... done.
    <stdin>: flushConsole: does not exist (No such file or directory)

    Process ghci finished

Any pointers?  - Conal
