There are some library components that have bogus pinnumber attributes 
of pin1, pin2 etc.

grep your system for these and either delete them or repair them to 
pinnumber=1

I understand you've moved on ... but beware.  Having been hosed, I 
recommend making your own set of transistor symbols and footprints. 
There are not that many, and they will be then suited to your type of 
work and methods.  If you're designing with transistors you owe this one 
luxury to yourself.

If anyone wants to get on top of this and fix the libraries I am game 
and would be more than happy to go through and hand edit a good set of 
symbols using EBC, GSD, SGD, CBE etc in the symbol names.
