[Users] mediaproxy error

Hi, I tried the lateset mediaproxy. When starting, got these errors and dispatcher won't start, /var/log/syslog:Sep 5 10:45:57 sip-1 proxydispatcher[4227]: File "/usr/local/mediaproxy/proxydispatcher.py", line 65, in ? /var/log/syslog:Sep 5 10:45:57 sip-1 proxydispatcher[4227]: File "/usr/local/mediaproxy/modules/dispatcher.py", line 39, in ? /var/log/syslog:Sep 5 10:45:57 sip-1 proxydispatcher[4227]: File "/usr/local/mediaproxy/modules/accounting.py", line 14, in ? /var/log/syslog:Sep 5 10:45:57 sip-1 proxydispatcher[4227]: File "/usr/local/mediaproxy/modules/mysql.py", line 8, in ? #ls /usr/local/mediaproxy/modules/ accounting.py daemon.py dispatcher.py mysql.py request.py serialize.py version.pyc accounting.pyc daemon.pyc dispatcher.pyc mysql.pyc request.pyc utilities.py configuration.py datatypes.py external options.py rtphandler.py utilities.pyc configuration.pyc datatypes.pyc formatting.py options.pyc rtphandler.pyc version.py Any suggestion?
