 When building readline on a Mac OS X with the GNUreadline framework in
 /Libraries/Frameworks, the build fails:
 {{{
 $ runhaskell Setup.hs build
 Preprocessing library readline-1.0.1...
 Building readline-1.0.1...
 In file included from include/HsReadline.h:7,

                  from HsReadline_cbits.c:1:0:

 /Library/Frameworks/GNUreadline.framework/Headers/readline/readline.h:36:31:
      error: readline/rlstdc.h: No such file or directory
 ...
 }}}
 This is in spite of:
 {{{
 $ runhaskell Setup.hs configure
 Configuring readline-1.0.1...
 ...
 checking for GNUreadline.framework... checking for readline... yes
 checking for rl_readline_version... yes
 checking for rl_begin_undo_group... yes

 checking for rl_completion_word_break_hook in -lreadline... yes
 ...
 $
 }}}
 This problem affects the tnaur osx buildbot slaves after I have installed
 the GNUreadline framework in /Libraries/Frameworks. See
 http://darcs.haskell.org/buildbot/all/tnaur%20PPC%20OSX%20stable/builds/29
 /step-stage1/0 for an example of this. Earlier, the tnaur osx buildbot
 slaves have have avoided this problem by simply not detecting readline
 and, therefore, never attempting to build the readline library.

 The enclosed patch introduces a fix for this, changing the readline.cabal
 file. Please note that this is included for illustration only, it is not
 intended to be the solution to this problem.

 Best regards
 Thorkil
