I don't know. What is it?

SPICE will think this is a diode whose model is named "200".

Need a model named "ln4007"

Zener? Needs to be Dsomething. And you need a bzx55c model.

Note that there are no subcircuits or models distributed with gEDA.  
They are generally the intellectual property of the manufacturer, so  
you have to go and find them.

This is much too complex a circuit to be your first SPICE sim. I  
suggest starting much smaller. Seriously consider verifying that  
resistors follow Ohm's law for your first try (no, I am not trying to  
insult you: SPICE is *hard* to use).
