[CentOS] ContOS5 and Samba-Vscan

Hi,

I am running a CentOS 5 file server in our Windows network and I wanted 
to add a anti virus scanner. I got a clamav package from atrmps.net, but 
the samba module samba-vscan is missing. So I am not able to integrate 
clamav as an on-demand scanner.
Does anyone know, where I can get the samba-vscan module?

Thanks
