      Type:  defect         |       Status:  new    
  Priority:  high           |    Milestone:         
 Component:  Cabal library  |      Version:  1.6.0.1
  Severity:  normal         |     Keywords:         
Difficulty:  unknown        |   Ghcversion:         
  Platform:                 |  
----------------------------+-----------------------------------------------
 When checking to see if the C libraries are available, Cabal isn't using
 the LD options that it has been given.

 This example is using GHC's `ghc-cabal` program, but that's just a thin
 wrapper around the Cabal library. It looks like it's in `checkForeignDeps`
 in `Distribution.Simple.Configure` that it goes wrong. Note that `--ld-
 options="-L/usr/local/lib "` is passed, but not used in the `gcc` commands
 that do the linking.

 ghc-cabal: Missing dependency on a foreign library:
 * Missing C library: gmp
 This problem can usually be solved by installing the system package that
 provides this library (you may need the "-dev" version). If the library is
 already installed but in a non-standard location then you can use the
 flags
 --extra-include-dirs= and --extra-lib-dirs= to specify where it is.
