This came (basically) from the gtktest.c program in the distribution, so I 
can't claim any real credit.

Your callback for selection should look like this:

void rpmCListCallback (GtkCList *clist, gint row, gint col,
                       GdkEvent *event, gpointer data) {
.
.
.
}

and when you set up the clist inthe first place, use a signal connect like:

gtk_signal_connect (GTK_OBJECT (rpmCList), "select_row",
                    (GtkSignalFunc) rpmCListCallback, NULL);

In your callback, row & col will be set to the users selection.  Works for 
me...
