Hamish and Chitlesh, how about it?
Ok, I'll try to update Fedora's gnucap this weekend.

The problem is with the build system.

Thanks for all the replies everyone, but I think I should have started
with something a little simpler and built off that. Now I can't even
model a simple AC source in series with a resistor...I tried to do it in
straight gnucap and eliminate gschem to try to narrow down the culprit.

In this case, the solver will not need to add extra steps internally.
You specified a sin generator, whose output is a simple function of
time, and a resistor. The whole circuit is memoryless. At 60Hz, the
period is just 16.6ms. With a 10ms step size, of course you're going
to see an aliased

Al, I think it would really help if you made a release. All of the distros are
stuck at 0.35,

Well, this is a gnucap question, not a gschem question. But if the tran command
