Could you test my scheme ?
Please add scheme below to .gEDA/gschemrc and add keymap "1" key ->
"direct-gwave" function like this 

	("1" . direct-gwave)

gschem can be shown simulation result wave form directly(ofcurse, you
need ngspice and gwave).
I put sample schematic at 
	http://members.jcom.home.ne.jp/pnms/src/direct-gwave-test.sch

(define (direct-gwave)
  (let* ((filename-without-suffix (substring (get-selected-filename) 0 (string-index (get-selected-filename) #\.)))
         (filename-sch (get-selected-filename))
         (filename-cir (string-append filename-without-suffix ".cir"))
         (filename-raw (string-append filename-without-suffix ".raw"))
         (netlister "/usr/local/bin/gnetlist")

    (system (string-append netlister " -g spice " filename-sch " -o " filename-cir))
    (system (string-append simulator " -r " filename-raw " -b " filename-cir ))
    (system (string-append viewer " " filename-raw " &"))))

(define (simulation)
  (let* ((filename-without-suffix (substring (get-selected-filename) 0 (string-index (get-selected-filename) #\.)))
         (filename-sch (get-selected-filename))

    (system (string-append simulator " -r " filename-raw " -b " filename-cir ))))
