PIL doesn't recognize jpeg library under Mac OS

Question

Scripts like that:

from PIL import Image, ImageOps
img = Image.open('1.JPG')
thumb = ImageOps.fit(img, (200,200) , Image.ANTIALIAS, (0.5, 0.5))

cause this IOError:

Traceback (most recent call last):
  (...)
  File "/Library/Python/2.7/site-packages/PIL/Image.py", line 385, in _getdecoder
    raise IOError("decoder %s not available" % decoder_name)
IOError: decoder jpeg not available

How do I get jpeg support for my PIL? That issue seems to be well known but the existing threads don't solve it for me. I use brew and pip for my python packages and have already tried the following:

• brew install jpeg causes Error: jpeg-8d already installed
• brew install libjpeg causes Error: jpeg-8d already installed
• sudo pip install Pillow - installation works but does not change anything

How do I get jpeg support for my PIL installation? Any ideas?

I don't understand why, but reinstalling PIL fixed the issue:

sudo pip uninstall pil
sudo pip install pil
