Compiled the libjpeg v8, PIL 1.1.7 and and import for _imaging works on the system Python, but spouts this error inside the virtualenv:
libjpeg.so.8: cannot open shared object file: No such file or directory
here is the error run with a python -v interpreter inside the virtualenv
>>> import _imaging
dlopen("/home/ygamretuta/dev/py/django/lib/python2.6/site-packages/PIL/_imaging.so", 2);
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: libjpeg.so.8: cannot open shared object file: No such file or directory

I am using Ubuntu 10.10 and this is the uname-a output:
Linux ygam-desktop 2.6.35-28-generic #49-Ubuntu SMP Tue Mar 1 14:40:58 UTC 2011 i686 GNU/Linux
I am using Python 2.6
I followed the following guides already:
http://appelfreelance.com/2010/06/libjpeg-pil-snow-leopard-python2-6-_jpeg_resync_to_restart/
http://www.jooncode.com/2010/12/02/python-pil-jpeg-resync-restart-error-imaging-module-solve/

See an explanation here: Why can't Python find shared objects that are in directories in sys.path?
A quick fix is to add the directory that contains libjpeg.so.8
to your /etc/ld.so.conf
file, and then run ldconfig
Also if you are doing local Python installations you can also control dynamic linking on the session level using LD_LIBRARY_PATH environment variable::
export LD_LIBRARY_PATH=/srv/plone/python/python-2.6/lib
python
import _imaging
...
This way you cannot break your OS itself, even accidentally. (It happens: http://opensourcehacker.com/2011/08/31/zend-server-installation-potentially-kills-your-ssh/)
Compiling the library from source works too: http://www.ijg.org/files/
Make sure to use jpegsrc.v8.tar.gz if you're on a Unix like system though. jpegsr8.zip appears to be the MS version, and throws all the standard formatting issues while building.
maybe just install libjpeg
conda install -c conda-forge libjpeg-turbo
