cabal: Couldn't read cabal file "./Glob/0.1/Glob.cabal"

Cabal-1.4 cannot read some .cabal files that use new syntactic constructs added in Cabal-1.6. The cabal-install program does not handle this fact very gracefully.

Any ideas? As far as Hackage and the local index are concerned, 0.1 isn't even a recent version of Glob. Why should it be looking for the file?

It's a good point, it should not need to parse the .cabal file of the older version. However that's just a performance thing, the newer versions will have the same issue.

cabal-install version 0.5.1 using version 1.4.0.1 of the Cabal library

The solution is to upgrade: $ cabal install cabal-install $ cabal --version cabal-install version 0.6.0 using version 1.6.0.1 of the Cabal library Duncan
