Bug#866484: sympy: depends on obsolete python-imaging (replace with python3-pil or python-pil)

[Matthias Klose]

Package: src:sympy
Version: 1.0-3
Severity: important
Tags: sid buster
User: doko at debian.org
Usertags: imaging-pillow

One or more binary packages built from this source depends on or
recommends python-imaging, which is obsolete for some years now.
Please build the source using the python-pil package. If your
package doesn't need to be built with Python2, please consider using
Python3 and depend on python3-pil.

Planning to remove python-imaging for the buster release, so the
severity of this issues might be raised.
