[RdBSD]

Dear all, 

i've an error when i try to install samba-vscan on ports. 

The error say :

openantivirus/vscan-oav.c:179:33: invalid suffix "a" on integer constant
openantivirus/vscan-oav.c:242:33: invalid suffix "a" on integer constant
gmake: *** [openantivirus/vscan-oav.po] Error 1

gmake kavp or clamav 

Stop in /usr/ports/security/samba-vscan.
