I use gnetlist. Is it not the commonly used one with gEDA?
Are there any other suggestions?

Very helpful. I took an opportunity to change it to
M1 4 1 0 0 BS170
in my netlist and it worked fine. The result is a lot different from
LTSPICE but it may be due to the difference in the model. I just used
the BS170 model from the Internet.
Many thanks.
