Hia Dominic,
I've looked into this a bit. I think I may now be less confused. :-)

Ah! Is that the only file that is read-only? That makes sense since it's an original source file from your read-only source control system. The System.Directory.copyFile function does not copy permissions (though it does try to) but it does (unhelpfully) copy the read-only attribute.
It may not be but a lot of packages only have a LICENSE file. I'll have a look tomorrow.
Sure, I didn't mean that because it's only a license file it's ok. It's just that it makes sense given that it's one of the only files copied direct from the sources directory (rather than generated during the build). It took me a while to work out what was actually going on (and to realise it was different from the other permissions problems people have reported on Windows).
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.
Thanks very much. I'll try it out tomorrow.
Thanks. The fixes are now in Cabal HEAD and the Cabal-1.6 branch so use whichever is easier for you. Duncan
