Comment:

 This has to be reported upstream. Can you please open a ticket at
 http://www.cmake.org/Bug?

 (I wonder why CMake even searches for GTK during installation.)

 This most probably failed because of a bug in `FindGTK.cmake`. You could
 try two things. After "`port patch cmake`", edit `FindGTK.cmake`. The
 first thing you could try is to replace `gtk/gtkversion.h` with
 `gtkversion.h` in the following chunks of code:

 {{{
         _GTK2_GET_VERSION(GTK2_MAJOR_VERSION
                           GTK2_MINOR_VERSION
                           GTK2_PATCH_VERSION
                           ${GTK2_GTK_INCLUDE_DIR}/gtk/gtkversion.h)
 ...
 if(NOT GTK2_FIND_VERSION AND GTK2_GTK_INCLUDE_DIR)
     _GTK2_GET_VERSION(GTK2_MAJOR_VERSION
                       GTK2_MINOR_VERSION
                       GTK2_PATCH_VERSION
                       ${GTK2_GTK_INCLUDE_DIR}/gtk/gtkversion.h)
     set(GTK2_VERSION
 ${GTK2_MAJOR_VERSION}.${GTK2_MINOR_VERSION}.${GTK2_PATCH_VERSION})
 endif()
 }}}

 The second option would be to modify `GTK2_GTK_INCLUDE_DIR`, but I'm not
 yet sure how.

 (Oh, and the third thing to try would be to uninstall `Gtk.framework`. ;)
