f-prot mail scanner question

Is anyone using f-prot mail scanner with 8.2? Not the workstation version, but the mail scanner version. I'm having a bit of trouble installing it. Seems I can't get perl-Mime-base64 installed. Actually, I don't know where to find it and CPAN is giving me errors. Next question, do I really need the mail scanner version? Can I use the workstation version and have it called up by postfix? Right now I'm using AntiVir workstation trial that came with 8.2 and I want to switch (don't ask why....long story). Thanks, Tom
