>Description:
        Linking against glib2 (i.e. building gtk2+) on Mac OS 10.4 (Tiger)
        fails due to an unresolved symbol _res_9_init.
>How-To-Repeat:
        cd x11/gtk2; bmake build
>Fix:
        Apply the following (slightliy adapted) upstream fix to config.in as a
        patch, then rebuild configure using autoconf, merge with patch-aa/-ak:
