Thanks Mengu.
1) Yes, WSGIPythonHome is set.
2) No, just one Python version -- 2.6.6 (in a virtualenv)
3) The Apache config is identical between the application that works and
the one that doesn't, except for the obvious things that should vary, such
as the virtual host name, the names of the error log and pid file, the port
number , and so on. See below.
4) I'll try the mod_wsgi group.
