Install Cabal-dev on windows 7

问题:

I'm trying to install Cabal-dev on windows 7.

I've managed to get past the problem with not being able to build network by using this:

cabal install --constraint="network installed" cabal-dev 

However then I get this:

>cabal install --constraint="network installed" cabal-dev

Mikhail Glushenkov's recommendation worked

I cloned the git repo for cabal-dev and then build it like this:

runhaskell -isrc admin/bootstrap.hs

then I added

{windowspath ..}\cabal-dev\cabal-dev\bin

to my path and everything is working.

I can now run cabal-dev install in my yesod folder get yesod working finally.
