Re: gEDA-user: Error message when creating a SUBCKT

About the unused slots, it doesn't seems to be the problem.

When I add the 2 unused slots to my schematics and link theirs input pins to ground and output pin to NC symbol, drc2 removes the warning but the spice-sdb give me more "Invalid wanted_pin passed to get-nets [unknown]"

I've already use slots in another circuit without any problem.

Perhaps for the spice backend, but IIRC, spice-sdb renames each slot, so
U2 becomes.

U2.1
U2.2
U2.3
U2.4

e.g. 4 components instantiated. I might be wrong in the fine-print though.
