 Priority:  Normal            |  Milestone:
Component:  ports             |    Version:  2.3.1
 Keywords:                    |       Port:  py27-pyphant-imageprocessing
------------------------------+------------------------------------------
 The path-based approach for removing the py27-pil dependency as suggested
 in #44285 is not working in a straight-forward way for py27-pyphant-
 imageprocessing, as PIL is also a dependency on the setuptools level. The
 runtime plugin mechanism for adding the py27-pyphant-imageprocessing
 toolbox to py-pyphant will fail when it cannot resolve this dependency as
 it is based on pkg_resources. The Pillow/PIL fallback mechanism would also
 have to be implemented on the setuptools level.

 A possible solution could be to completely remove the py27-pil dependency
 from py27-pyphant-imageprocessing, replacing it by py27-Pillow and
 patching the setup.py file to also refer to Pillow instead of PIL.
