Hello sir I very much sorry You wrote to me : "Sorry, but I don't understand what configure script you are trying to call. If you will install omniorb normal way (apt-get install omniidl4 omniidl4-python libomniorb4-dev libomnithread3-dev', you should not have aby such problems." I've install all mentioned on M GUERRA before install FRED. Do you remember when I had problem with fred-pyfred  (witch not started) on DEBIAN and when I used fred-manager for install. I had solved this with installing omniORBpy and fred-pyfred started. So I think that I can solve this same problem on Ubuntu with omniORBpy installation. Only fred-pyfred server don't start on UBUNTU. On DEBIAN I have to delete FRED database for restarting servers otherwise it stop on PostgreSQL interface.
