rpm for clamav

[sasa]

Hi, on Fedora Core 3 with clamav-0.88.1 when I try to build rpm files for 
0.88.2 version I have :

[root at mail redhat]# rpmbuild --target i386 -ba SPECS/clamav.spec
Building target platforms: i386
Building for target i386
error: Macro %cvs_date has empty body
error: Macro %devels has empty body
error: Failed build dependencies:
        libunrar3 is needed by clamav-0.88.2-1.i386
        libun7zip is needed by clamav-0.88.2-1.i386

..but which rpm packages I must installed before ??
thanks.
