>Description:
programs from xdg-utils bomb out randomly depending on whether various
directories at absolute paths exist or not, none of which are in standard
pkgsrc locations.

Found by code inspection after packaging fotoxx failed with:
        xdg-desktop-menu: No writable system menu directory found.
        
>How-To-Repeat:
        
( cd /usr/pkgsrc/graphics/fotoxx && make )
>Fix:
        at least xdg-desktop-menu is full with absolute paths that may or may
        not exist in a pkgsrc environment, none of which are in standard
        pkgsrc locations and are inappropriate for USER_DESTDIR in any case.
        Locations checked include but are not limited to e.g. /usr/share,
        /usr/local/share, /etc/xdg.
