Ah, the problem is that scm_is_exact_integer has been introduced in Guile 
2.0.10 [0].  I wasn't aware of that because I tested with Debian stable, 
and the current stable (jessie) has Guile 2.0.11.

The fix for that would be to check for a more recent version of Guile; but 
that won't help you right now.  You have one of the following options:

1. Comment out lines 28 and 29 in xorn/src/cpython/guile/scm2py.c.  As far 
as I can see, it should still work without these.

2. Switch to the legacy version of the netlister.  You can do so by adding 
(set! use-legacy-frontend #t) to your gnetlistrc file.

3. Upgrade to the next LTS release, Xenial Xerus.

Either of these should fix it for you.

Roland
