Comment (by thorkilnaur):

 The basic problem seems to be that Mac OS X'es have this additional and
 different way of setting up paths for include files and libraries.
 Essentially, this forces a program like GHC to more or less duplicate this
 mechanism. And to a certain extent this has happened: GHC has a -framework
 option to pass to the Mac linker and a -framework-path option to pass
 something to the Mac linker -F option.

 But GHC doesn't have an option that matches the Mac gcc -F option: GHC
 doesn't do any Mac-like framework management similar to what the Mac gcc
 does. And that is really what you are missing, if I understand your
 comment correctly.

 So in that situation, I still believe that it is preferable to let the
 Cabal-packaging of the readline library handle these differences.
 Likewise, various fixes could probably be concocted to solve the Shellac-
 readline problem (such as the use of symbolic links or installing the GNU
 readline library in one of the places that it is normally placed in).

 Best regards
 Thorkil
