I think this is related to your previous error number 3... thus I hope
it is fixed in the last release.

If you want to get your last error fixed, and you can recompile the
code, you only have to patch gnetlist/src/g_netlist.c as shown in CVS
(version 1.39 to 1.40). It is a simple patch that won't hurt you.

The changes made to the symbols are mainly because of missing or wrong
pintype and pinlabel attributes. The pintype attribute is an important
one for the drc2 backend, because it checks if an output pin is
connected to another output pin, for example.
If you don't update the symbols, you just will get warnings like
"unknown connected to unknown", which means that a pin with pintype
"unknown" is connected to another pin with pintype "unknown". You can
ignore them if you want.

The drc2 backend is highly configurable, so you can skip the pintype
test if you want. See the documentation inside gnet-drc2.scm file (look
for dont-check-pintypes-of-nets).

Carlos
