Thanks, your recipe was helpful to get me started. I'm trying to turn this into a Windows batch file, which I'll post back for your consideration (work-in-progress copy below).
I notice that the Win32 distribution of GHC does not include ar, so I've located and downloaded a MinGW kit.
It might be possible that you can use gcc's ld to build the archive, using some options like "--dll --out-implib file.a" although I can't be sure from the manual page whether this is really the right thing.
Compiling the source kit, I find module: Text/XML/HaXml/Validate.hs imports FiniteMap when what is provided by GHC is Data.FiniteMap.
Yup, FiniteMap was the old name (still available in package lang I think), but Data.FiniteMap should be essentially identical.
Copying the .hi files to the imports directory tree, I find that one existing file (from the GHC installation) is requested to be overwritten: Overwrite C:\DEV\ghc\ghc-6.2\imports\Text\PrettyPrint\HughesPJ.hi
Ah, yes, Text.PrettyPrint.HughesPJ is only included in the HaXml distribution for backward compatibility with older compiler versions that didn't have it. Probably best to remove the source from the tree before building.
ghc-pkg.exe --add-package 0
I always get the same error too (on Linux and Solaris), even though the file does exist. Must be a bug in ghc-pkg. Regards, Malcolm
