Hm, python-mapnik gives me strange messages. This is not my backport only
but also your version which I ran in a stretch chroot:
# python
Python 2.7.11+ (default, May 9 2016, 15:54:33)
[GCC 5.3.1 20160429] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import mapnik

Is this harmless?
Looks like this has already been reported upstream:
