That repo is a little strange, I get this:

$ git clone git://git.savannah.gnu.org/gnucap/gnucap-plugins.git

It seems it consists of a few non-connected branches.

Don't you get the connections from the netlist ?

 ./bootstrap works fine here, but
 ./configure gives:
checking dynamic linker characteristics... (cached) GNU/Linux ld.so
checking how to hardcode library paths into programs... immediate
./configure: 16616: GC_CPPFLAGS+= -I/usr/local/include/gnucap: not found
./configure: 16618: CPPFLAGS+= : not found
checking l_dispatcher.h usability... no

 so something is strange.

I think something is not good enough with guile-2.0, and that the
libgeda package should be updated for a newer guile version.
Bug your distro about that.

Wouldn't it be best if geda/lepton supported gnucap instead of the 
other way around ?

The guile 1.8 to 2.x step was a bit painful in general.
My guess is that geda with its xorn need some time to evolve out of
the guile dependancy and strange things happens there, at least for me.
So currently I'm mostly working with lepton.
so... my gueass is that geda/lepton changes faster than gnucap, and
that is why they should support gnucap and not the other way around.

Yes ?
