[galaxy-dev] Problem with Mako and Beaker egg...

Hi, I'm trying to install Galaxy in a production environment. Since I set Postgres DataBase, I've got this warning when I launch any tool: /WARNING:galaxy.eggs:Warning: Beaker (a dependant egg of Mako) cannot be fetched/ And this warning is print in STDERR... so the tool failed... I don't know why it can't fetch Beaker egg... I aldready try to remove : - $GALAXY_ROOT/eggs/Beaker-1.4-py2.5.egg - $GALAXY_ROOT/eggs/Mako-0.2.5-py2.4.egg - $GALAXY_ROOT/eggs/Mako-0.2.5-py2.5.egg but I've got still the problem. I'm open to any solution !! Many thanks for your help, Marc
