I suspect that you're using a version of gEDA compiled against guile
1.8, prior to a necessary fix. Guile 1.8 doesn't support "nil" any more.

The best plan is to upgrade to the latest gEDA release (1.4.0), as it
has _MANY_ bug fixes.

How / where did you get gEDA from? (compiled from source / distro
package - which distro and version?)

Alternatively, find the .scm files in /usr/share/gEDA/scheme, and find
occurrences of "nil" using "grep nil *.scm". The substitutions suitable
are either "#f" or "'()" (no quotes in either case). I'd use #f unless
the comments around that usage suggest the variable is a list.

I'd not trust the output netlist to be correct unless this is fixed,
since as soon as the ERROR: .... is emitted, no further processing takes
place.
