unbound v1.6.0 python module on debian 9

[Christopher Hearn via Unbound-users]

I’m trying to set up a server running unbound and a python script.  This is 
working OK on an older server running version 1.4.2.  On the newer one, I can’t 
seem to get unbound to see the python script dependencies.  I do recall on the 
old server, this was because chroot was enabled.  Once I disabled it in the 
config file via chroot: “”, it was fine.  It’s disabled on the new one too, but 
still doesn’t seem to help.  If I symlink the requested file from 
/usr/lib/python2.7/dist-packages/unboundpython.py to /etc/unbound/, that 
resolves that error, but more come up because of course it can’t see the other 
libraries.  This leads me to believe that unbound isn’t looking out of 
/etc/unbound/ even though chroot is disabled.  Is there something else I’m 
missing?
