[Haskell-cafe] building "encoding" on Windows?

I'm trying to help a non-Haskell person build wyvern (shameless plug  
in case you like go: http://dmwit.com/wyvern), but (s)he's having  
trouble building the "encoding" library. Has any Windows person done  
it successfully or is willing to try it?

I tried contacting the "encoding" maintainer a few days ago, but  
haven't heard back.


P.S. I thought it might just be a missing library, but the encoding  
library itself comes with "system_encoding.h".

Sorry no
cabal install HaXml

goes well (but takes  longer than 2 minutes)
Cabal install sgf not

more specific:
last lines are
Configuring encoding-0.6.3...
Setup.exe Missing dependency on foreign library:
* Missing Header file: System_encoding.h
This problem can usually be solved by installing the system package that
provides this library (you may need the "-dev" version). If the library is
Allready installed but in a non-standard location then you can use the flags
--extra-include-dirs= and --extra-lib-dirs= to specify where it is.
CABAL: Error: some packages failed to install:
encoding-0.6.3 failed during the configure step. The exception was:
exit: ExitFailure 1
sgf-0.1.1 depends on encoding 0.6.3 which faild to install.

Hope you can solve it
