Well, while playing with this I noticed that version 35 has been released. Removing the erroneously included files is no longer needed.  Thanks for the tip for including pre_check!  The only thing I haven't included is a libngspice dependency in ngspice, since it doesn't really seem necessary and doubles the install size for those just looking to use ngspice (admittedly install size probably isn't a big deal either), but I can add it too if we want to go that way.
