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 instal
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.
