----------------------------------------+-----------------------------------
 The code in the Portfile to detect the macports installation of Grass 6.4
 as /Applications/GRASS-6.4.app fails, and the flag sent to the configure
 command is actually --with-grass=/opt/local:

 In order to get around the bug where gdal-grass has a false dependence on
 the nonexistent port grass64, I modified the following lines in the
 Portfile
 {{{
 # Select Grass version

 variant grass64 description "Builds against grass64" {
         depends_lib-delete              port:grass
         depends_lib-append              port:grass64

         configure.args-delete   --with-grass=${prefix}/lib

         if {[file exists ${applications_dir}/GRASS-6.4.app]} {
                 configure.args-append   \
                         --with-
 grass=${applications_dir}/GRASS-6.4.app/Contents/MacOS/
         } else {
                 configure.args-append --with-grass=${prefix}
         }
 }

 }}}
 to read

 {{{
 # Select Grass version

 variant grass64 description "Builds against grass64" {

     configure.args-delete       --with-grass=${prefix}

                 configure.args-append   \
                         --with-
 grass=${applications_dir}/GRASS-6.4.app/Contents/MacOS/lib
 }
 }}}

 Even with this modification, configure fails to find Grass to its
 satisfaction.
