Question

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

and here are the paths:

Answer 1

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
