[syslog-ng] build problem on FreeBSD 7.2

[ko]

Hi all,
I'm trying to build v3.0.3 from source (with sql support) on a fresh 
install of FreBSD 7.2, and I have the following error when I lauch the 
make :  "afsql.c:36:21: error: dbi/dbi.h: No such file or directory"

I think I miss a library, something nedded for database support but I 
don't know what ?

Could anymone help me ?

Thanks a lot.
Karl.
