[Asterisk-Users] SIP/IAX2 mysql auth + FreeBSD

[Lerale Erwan]

Hello,

I'm trying to do this :
http://www.voip-info.org/tiki-index.php?page=Asterisk%20sip%20mysql%20peers
on a FreeBSD (4.9-RELEASE-p11) with mysql 3.23.58 (from the ports)

but the only thing i'm getting is :
Aug 18 20:22:27 WARNING[135151616]: /usr/lib/asterisk/modules/chan_sip.so: Undefined symbol "mysql_real_escape_string"
Aug 18 20:22:27 WARNING[135151616]: Loading module chan_sip.so failed!

The Mysql libs seems to be running correctly (cdr_addon_mysql.so is 
working).

I'd really don't know where to begin my search... 

Maybe someone can help ?

Cheers
