Read the stuff at the bottom of this page:

http://www.brorson.com/gEDA/SPICE/x150.html

(and the rest of the doc if you haven't).

Also, there is an example hierarchical schematic in the examples
directory of the gEDA/gaf sources.   It is called RF amp or
something like that.  If you can't find it in the gEDA examples, you
can download it here:
