Are you using pspice or ngspice? Looks like you are on linux from your 
emails, but maybe you use pspice under wine? Then you could also use 
ltspice under wine. Or if you have ngspice running you could use 
xcircuit which is easier for small circuits spice simulation than 
geda. You can run xcircuit anyway as it write the spice netlist the 
way you want.

In other words, what do you want to do? Do you only want to get the 
job done, or do you want to get it done in geda?
