Jfets are not built-in.  They are in a plugin, that comes in a 
different package.  Get the "models-spice3f5" package, and 
there is a jfet in there.  There are also jfets 
in "models-jspice" and "models-ngspice".  They all work the 
same so it doesn't matter which one you get.

The snapshot has a lot of new stuff that isn't in the stable 
version.  It grew fast without the proper documentation.  My 
highest priorities now are to make sure it all works the way it 
should, and bring the documentation up to date.
 
Get ".......-models-spice3f5....

Untar in the same place where gnucap is, so it makes a 
directory "plugins" in the gnucap directory.

Look at the file "README" and follow the directions there.
