In version 3.3.0 python-pillow replaces libpng as dependency.

Package 3.3.0-1 :

$ cat test.py
import matplotlib.pyplot

$ python test.py
Traceback (most recent call last):
File "test.py", line 1, in <module>
import matplotlib.pyplot
File "/usr/lib/python3.8/site-packages/matplotlib/pyplot.py", line 36, in <module>

import matplotlib.text as text
File "/usr/lib/python3.8/site-packages/matplotlib/text.py", line 16, in <module>
from .textpath import TextPath # Unused, but imported by others.
File "/usr/lib/python3.8/site-packages/matplotlib/textpath.py", line 11, in <module>
from matplotlib.mathtext import MathTextParser
File "/usr/lib/python3.8/site-packages/matplotlib/mathtext.py", line 27, in <module>
from PIL import Image
ModuleNotFoundError: No module named 'PIL'


Suggestion:

Make python-pillow a dependency and drop it from makedepends and optdepends.

Drop libpng from depends.

Some additional information below about setup.py which removed libpng for pillow. The commit is included in the v3.3.0 tag. setup.py explicitly lists pillow as a dependency.
