Development version won't recognize my netlist

I am having trouble running my netlist in interactive mode. Based on reading
the mailing lists, I am guessing that it has something to do with the
language option, but I have not yet been able to figure out how to set it to
run spice.

I compiled the 2008-02-11 development version of gnucap. When I run my
circuit, it seems like every statement is wrong:

I ran the 2007-12-16 version of gnucap. Since previously I was trying to
make my own model with a reference designation of B, and I had not
implemented my model with this version of Gnucap, this is what I would
expect to see.
