 Hi,

 cabal-install version 0.8.2
 using version 1.8.0.2 of the Cabal library

 This bug was originally reported by a Debian user.

 the `cabal' executable, when run on the attached sample library, chooses
 base 3.0.3.2:

 $ cabal -v configure
 [...]
 Configuring foobar-0.0...
 Dependency base ==3.0.3.2: using base-3.0.3.2
 [...]

 whereas, the library (via Setup.hs) correctly gets base 4.2.0.0, probably
 due to ghc's hiding of the earlier version

 $ runhaskell Setup.hs -v configure
 Configuring foobar-0.0...
 Dependency base -any: using base-4.2.0.0
 [...]

 cabal-install should probably perform the same hiding that ghc does.

 Cheers,
 Iain
