MailScanner 4.78.17 doesn't detect viruses, have checked tmp permissions and no symlink, reinstalled clamav (worked in 4.77.10)

[Sunny Forro]

I've rerun the ./install.sh script - again to no effect. However, I
discovered that MailScanner is properly parsing mcafee's output but not
clamavs. When I lint with my virus scanners set to "clamav mcafee" it
picks up Eicar from mcafee, but nothing from clamav. If I set it to
"clamav" it doesn't pick up Eicar at all.

Side Note: I have a paid version of McAfee that I have used until
recently, when I discovered that the latest release of mcafee for BSD
still relies on an outdated compatibility library (compat3x) that
doesn't properly install and isn't included in any release since
FreeBSD5. It also spikes my CPU to 100% while scanning mail and slows
the whole process to a crawl. Running clamav only with a previous
release of MailScanner produces more reliable results because when  my
CPU hits 100% (using mcafee and clamav) mail begins to flow through
completely untouched.
