[gnue-appserver] fails to start while scanning NIC information under FreeBSD

Hi,

I'm in the course of evaluating GNUe.  I'm running a server with FreeBSD 5.4
(tried also SuSE 9.3, but didn't succeed to get so far as for FreeBSD).

* I successfully resolved the prereqisities for gnue-common 
  and gnue-appserver,
* initialised the gnue DB with gnue-setupdb
* edited the /usr/local/gnue/etc/connections.conf and .../gnue.conf
  according to gnue-common-0.5.14/INSTALL

Thought, the server should be ready to execute gnue-appserver, but I get
following failure:

-bash-2.05b$ gnue-appserver 
Traceback (most recent call last):

Is this specific to FreeBSD?  Has anyone experiece with this failure?
(New to GNUe and Python, so any help welcome.)

Thank you.
