i think it works now, although i still get a permission denied error, the package appears registered. ghc-pkg list | grep network shows the package and i can install further packages. so i guess the problem is solved now... not sure which step made it work in the end.. probably the admin rights. emmanuel On Fri, Dec 21, 2012 at 9:44 PM, Emmanuel Touzery wrote:

running cmd.exe as admin or marking ghc-pkg to be run as administrator does not help.

hmm maybe a step forward...

running: cabal install network --reinstall -v

the final output lines are in fact:

Registering network-2.4.0.1... C:\ghc\ghc-7.6.1\bin\ghc-pkg.exe update - --global --user cabal: permission denied

this is using GHC 7.4.1 and using the cabal which came with the latest haskell platform. I wiped clean my $HOME/cabal and $HOME/ghc, $HOME being %AppData%.

In $HOME/cabal/config I set those options: library-profiling: True user-install: True

Any idea?
