For example, when installing Satchmo shop under virtualenv:

../bin/clonesatchmo.pyhe Python Imaging Library is not installed. Install from your distribution binaries.


../bin/clonesatchmo.py
The Python Imaging Library is not installed. Install from your distribution binaries.

Though it clearly is there, installed by easy_install PIL command:

ls ../lib/python2.5/site-packages/PIL-1.1.7-py2.5-linux-x86_64.egg
ArgImagePlugin.py	 ExifTags.py		  GimpGradientFile.pyc...

Does anyone know if this problem is with PIL itself, eggified PIL or something else?

In any case, there is an easy workaround: use system-wide PIL (sudo apt-get install python-imaging) and symlink PIL from your site-wide installation under the isolated Python environment:

(satchmo-py25)mulli% pwd
/srv/plone/mmaspecial/satchmo-py25/lib/python2.5/site-packages
(satchmo-py25)mulli% ln -s /usr/lib/python2.4/PIL .
That works for now, but I’d like to learn how to make virtualenv and buildout install PIL egg bullet-proof way.
