The core routing setup uses 'routes' which is set up to use directory scanning to find controllers. This can error out, as seen below, if there is permission issue. This directory scanning isn't necessary, since we use object dispatch for all the routing.

    allura:db/6408

    To test: 

    mkdir Allura/allura/controllers/tmp
chown root:root !$
chmod 700 !$
/etc/init.d/httpd restart

    That'll fail on master, should work fine on this branch
