Sorry for the delayed reply.
Where is the package/module called 'host_cde' installed?
If not on standard Python module search path and you have set sys.path
explicitly to add parent directory, or used python-path option to
WSGIDaemonProcess, clearly state which was used.
The logs show:
[Tue Dec 30 10:36:52 2008] [info] mod_wsgi (pid=369): Adding
'/home/web/xxx/pynclude' to path.
[Tue Dec 30 10:36:52 2008] [info] mod_wsgi (pid=369): Adding
'/home/web/xxx/xxx.flibuste.net/pynclude' to path.
This suggests to me that using python-path option. These first entries
though are for main interpreter instance, ie., %{GLOBAL}.
Look down further and you will see:
[Tue Dec 30 10:54:36 2008] [info] mod_wsgi (pid=369): Create
interpreter 'xxx.flibuste.net|/cde/serv_cde.wsgi'.
[Tue Dec 30 10:54:36 2008] [info] mod_wsgi (pid=369): Adding '' to path.
Thus, when it later creates sub interpreter, the path seems to have
been mangled in stored configuration and thus only empty path added
and not the two directories above where your package/module possibly
is. Thus can't find module.
