Who's in charge of ucbmpeg and ucbmpeg_play ? These packages are still a.out. I've tried to rebuild them, but there's little doc (read no doc), and it needs Tcl and Tk. Which versions ? I had problems with both Tcl 7.4 Tk 4.0 and Tcl 7.5 Tk 4.1. I had to link with Tcl 7.4 and 7.5 plus Tk 4.1. Duh ! Phil.
