I made a modification to resolve a minor inconvenience I noticed. Trying pkg_dig with python-tkinter was giving me this result:
[EMAIL PROTECTED] msid $ pkg_dig python-tkinter *- Package matched: python-tkinter-2.4.3p0 |- Dependencies: tcl-8.4.7p1 python-2.4.3p0 tk-8.4.7 |- Required by: none |- You may also delete: tk-8.4.7 [EMAIL PROTECTED] msid $ The problem here is that tcl-8.4.7p1 can be deleted as well since it is required only by tk-8.4.7 which, as shown above, can be safely removed. So, I made it check if any dependency depends on another as well. The result of this change: [EMAIL PROTECTED] msid $ pkg_dig python-tkinter *- Package matched: python-tkinter-2.4.3p0 |- Dependencies: tcl-8.4.7p1 python-2.4.3p0 tk-8.4.7 |- Required by: none |- You may also delete: tcl-8.4.7p1 tk-8.4.7 [EMAIL PROTECTED] msid $ I forgot to mention from the beginning that the script is totally harmless. It does not change anything on your system. It serves only for informational purposes. Finally, refetch, test, send feedback. http://black.daemons.gr/msid/scripts/pkg_dig -- Sideris Michael http://black.daemons.gr/msid/
