It won't as PYTHONPATH from root account will not propagate through
Apache startup.

Please provide me the exact output from running the following:
echo $PYTHONPATH
The run command line Python and inside of Python shell do:
import sys
print sys.version
print sys.prefix
print sys.path
import sphene
print sphene.__file__
import sphene.community
print sphene.community.__file__
For both the directories containing those __file__ items, do:
ls -las /some/path
Also do this for all directories back up to root file system.

Add:
print sys.version
print sys.prefix
import spene
import sphene.community
Send me the full output of paths and version plus the error message
from Apache error logs.
By sending me actual output then I can evaluate it and not have to
guess whether it is what is expected.
