The solution I think, is never to copy the read-only attribute when installing files. It's thoroughly unhelpful. I've got a patch to do this which I shall push to Cabal HEAD shortly. If you have a moment to help me test that it would be much appreciated.
I've attached a darcs patch against the Cabal-1.6 branch (rather than the head branch). darcs get --partial http://darcs.haskell.org/cabal-branches/cabal-1.6/ If you or anyone else can test it on Windows that'd be great. I checked it by setting the read-only attribute on a LICENSE file and where previously the attribute would get copied (preventing further re-installs) it is now not copied. On Unix it should solve this problem: http://hackage.haskell.org/trac/hackage/ticket/93 Though I've not tested that yet. The patch for the 1.6 branch is fairly minimal and doesn't change any API. In Cabal HEAD I'll do it slightly differently so that the code is more consistent and comprehensible, but it involves api changes to exposed utility functions. Duncan
