NdoUtils 1.4 error with Mysql

Hi,

I have performed throughout the procedure but when I launch the daemon ndo2db
(/usr/local/nagios/bin/ndo2db-3x -c /usr/local/nagios/etc/ndo2db.cfg)

I get this error :

“Support for the specified database server is either not yet supported, or was not found on your system.”

Nagios 3.0.6
Ndoutils 1.4b7

What should I check?

Thanks!
