Weird dependency failure log

Hi, all,

Hackage shows a log failure for 'bindings-gsl':

     Configuring bindings-gsl-0.1.1...
     cabal-setup: At least the following dependencies are missing:
     bindings-DSL ==1.0.*

But here is, at version 1.0.1, no building problems:

     http://hackage.haskell.org/package/bindings-DSL

There's one thing special about bindings-DSL. It's
a package with a set of macros for hsc2hs, and contains
no Haskell code. Maybe this revealed some hidden error
in package dependency checking.

Thanks,
Maurício
