hello sir

I have finished to install FRED but fred-pyfred server don't start .

when I do fred-server status I have  :

                                               fred-pyfred is stopped
                                               fred-rifd is running
                                               fred-pifd is running
                                               fred-adifd is running

And when I do fred-pyfred start it send back :

                                              Traceback (most recent call last):
                                              File "./root/bin/fred-pyfred", line 13, in <module>
                                                        import pgdb
                                              ImportError: No module named pgdb

 Have you a solution for this ?

                               thank you
