 Hmm, this is strange.  dns_test.py explicitly import isc.acl.acl
 before line 19 that triggered the exception above:
 {{{
 from isc.acl.acl import LoaderError, Error, ACCEPT, REJECT, DROP
 from isc.acl.dns import *
 }}}
 which should involve loading .libs/acl.so, which defines
 isc::acl::python::po_LoaderError.

 Right now I have no idea why this happened or how we can work around
 it (without breaking the MacOS build).  I'll try to reproduce it on
 bind10.isc.org.
