I think it's probably caused from "Tix" (Tk Interface Extension), an add-on for the Tk widget set, package. Please try to check it first, I've found it is very important to call graphical setup for hspice. Anyway, as above guy said, you can manually extract and configure software from you source files. However, "<hspice dir>/bin/config" also need proper "Tix". Just unpack and set license path may be work, but I'm not sure it can work with full features unless you know how to set configured files properly.
