@rapadura answer is correct in that you don't have direct access to the SetEnv values in your Apache config, but you can work around it.

If you add a wrapper around application in your app.wsgi file you can set the os.environ on each request. See the following modified app.wsgi for an example:

activate_this = '/var/www/michel/testenv/env/bin/activate_this.py'
execfile(activate_this, dict(__file__=activate_this))

from os import environ, getcwd
import logging, sys

from testenv.webui import app as _application

# You may want to change this if you are using another logging setup
logging.basicConfig(stream=sys.stderr, level=logging.DEBUG)

LOG = logging.getLogger(__name__)
LOG.debug('Current path: {0}'.format(getcwd()))

# Application config
_application.debug = False

def application(req_environ, start_response):
    environ['MYAPP_CONF'] = req_environ['MYAPP_CONF']
    return _application(req_environ, start_response)

If you have set more environment variables in your Apache config, then you need to explicitly set each of them in the application wrapper function.
