 I tried to configure a package with
 {{{
   Cabal-Version: >= 1.2 && < 1.3
 }}}
 in its cabal file. "ghc-pkg list" states i have both "Cabal-1.2.4.0" and
 "Cabal-1.4.0.1" installed. The configuration ("runghc Setup.lhs
 configure") fails with the following message:
 {{{
   Warning: grapefruit-frp.cabal: This package requires Cabal version:
 >=1.2 &&
   <1.3
   Configuring grapefruit-frp-0.0.0.0...
   Error: This package requires Cabal version: >=1.2 && <1.3
 }}}
 After "ghc-pkg unregister Cabal-1.4.0.1" everything works.

 (I stumbled upon this trying to compile grapefruit-frp
 (http://softbase.org/grapefruit/darcs/main/).)
