This Clearlooks port in MacPorts installs an outdated and no longer maintained version of Clearlooks (check the download link and website listed in the portfile). The current development tree for the Clearlooks theme engine has been moved from sourceforge to gnome.org (see also <https://bugs.edge.launchpad.net/inkscape/+bug/524496/comments/7> and Michael's follow-up comment).

If possible on Tiger you could test this issue with the Clearlooks engine that is included in the port 'gtk-engines2' (you need to deactivate gtk2+clearlooks first because these two ports install files to the same location and thus result in a conflict when activating. For packaging you need the updated version of 'osx-app.sh' (committed in r9206) because earlier versions check for a specific theme file that only gets installed with 'gtk2-clearlooks' but is never used by inkscape.

Maybe the radio buttons are rendered correctly with an updated version of the theme engine (which would explain the dated comments and bug status in the gnome bug tracker)?
