Recently when I have found good sources packages for ghc 6.12/6.10 on Hackage I've been forced to do some minor or major changes to the cabal files to make those packages to work under windows. Besides to fork and merge my fixes with github, what seems to be the best way/ good enough practice to take these modified builds to a couple of other windows boxes that only has a basic haskell platform installed?

I should prefer if I somehow could work with the cabal-install because that is what one normally use. Should one put the modfied build dirs on a shared/networked dir and mount from the targeted windows box? Say something like this:

on machine prepare

 cabal fetch foo
    cabal unpack foo
    cd foo
    edit .cabal and .hs
    cabal configure
    cabal build

On machine useanddevelopnormal

cd machinepreparemount
cd foo
cabal install
