[Bug 1112496] Re: python-imaging broken in raring

[Matthias Klose]

as a long-term solution, every rdepends should be patched as:

try:
  from PIL import Image
except ImportError:
  import Image

as a midterm solution, maybe ship a python-imaging-compat which holds
the .pth file

as short-term, maybe let python-imaging depend on python-imaging-compat.

Bug description:
  python-imaging in raring doesn't include a PIL.pth to point python at
  the library, so attempts to import modules from the package fail with,
  eg:

  rachel at rarity:/etc$ python -m ImageMode && echo ok
  /usr/bin/python: No module named Image

  When the PIL.pth file is manually created, so python can find it, the
  Image module itself still fails to load:

  rachel at rarity:/etc$ python -m Image
  Traceback (most recent call last):
    File "/usr/lib/python2.7/runpy.py", line 162, in _run_module_as_main
      "__main__", fname, loader, pkg_name)
    File "/usr/lib/python2.7/runpy.py", line 72, in _run_code
      exec code in run_globals
    File "/usr/lib/python2.7/dist-packages/PIL/Image.py", line 75, in <module>
      from . import ImageMode
  ValueError: Attempted relative import in non-package

  The ImageMode module that line seems to be trying to import, however,
  seems to import fine by itself:

  rachel at rarity:/etc$ python -m ImageMode && echo ok
  ok

  (I've confirmed that ImageMode comes from the same place, as if I
  remove PIL.pth again, the above line just returns the "No module named
  ImageMode" error)

  I've tried reinstalling python-imaging already. I note in any case the
  PIL.pth file is missing on the file list available at
  packages.ubuntu.com for raring.

  This is on Ubuntu Raring as updated from Ubuntu Quantal a few days
  ago:

  Affects me as it affects building/packaging XBMC post-frodo for
  raring. :-)
