Error ndoutils-1.4b7 support for the specified database


I try to use nagios 3 with ndoutils-1.4b7. I follow the installation guide with no problem (the user that I created created the table in the DB nagios in mysql…) and I execute the command:
/user/local/nagios/bin/ndo2db -c /usr/local/nagios/etc/ndo2db.cfg and I’ve got this error:
Support for the specified database server is either not yet supported, or was not found on your server

I check the conf ndo2db.cfg and it’s look good,
Someone add already this error?
