Thanks Gary -- that seems to do the trick.  Sorry I didn't spot the bogus symbol a long time ago.  I have reverted the changes I made yesterday and removed the ref to "error" and verified that the VM runs fine on FreeBSD 8.2.  (The binary is available on squeakvm.org in case it's useful to anyone.)

Regards,
Ian
