Good morning,
I did the reordering procedures of the sys.path variable.
Here is the mod_wsgi configuration in Apache. There is two pylons
application that I want to run, each with its own python virtualenv.
All the permissions of the virtualenv directories are OK (I can load
everything with another username).
I also tried changing the baseline environemnt, without succes
(WSGIPythonHome).
################### httpd.conf ###################

And here is the WSGI script file in question.

packages']

import site

prev_sys_path = list(sys.path)
# Add site-packages
for directory in ALLDIRS:
site.addsitedir(directory)
# Reorder sys.path
new_sys_path = []
for item in list(sys.path):
if item not in prev_sys_path:
new_sys_path.append(item)
sys.path.remove(item)
sys.path[:0] = new_sys_path
# Avoird ``[Errno 13] Permission denied: '/var/www/.python-egg'``

sys.path.append('/home/lemieulp/Public/Louis_HomePage')
os.environ['PYTHON_EGG_CACHE'] = '/home/lemieulp/Public/Louis_HomePage/

# Load the Pylons application
from paste.deploy import loadapp
application = loadapp('config:/home/lemieulp/Public/Louis_HomePage/

Here is the error log of Apache (with LogLevel set to debug).
