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.

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.

The solution is to upgrade:
$ cabal install cabal-install
$ cabal --version
cabal-install version 0.6.0
using version 18.104.22.168 of the Cabal library
