Fixed.

I'm not opposed to that, it's just that the debug feature was enough
for me.

| 3) I can't figure out how to use it :-)

You currently have to choose a terminal type, so try:

  print -deps -debug=FILE.gp

I chose this -debug=FILE syntax to simplify argument processing and
minimize the changes to the print function.
