The interpreter for lim is rhswish, which is a standard Tk wish program with lots of additions. You need to have rhswish installed. Since rhswish is based on Tcl/Tk, you need to have the Tcl and Tk shared libraries installed, as well as the Xpm shared libraries. And since lim calls rpp programs and verify-install, it requires that those be installed too. If you installed the Base and X Utils series, eveything will already be installed.
