security/amavisd-new start command not working with full path to rc script

[Miroslav Lachman]

"service amavisd start" is working fine (from commandline and crontab too)

But if it is called with full path to rc script it silently fails.

It is on FreeBSD 10.3-RELEASE amd64 GENERIC

Does anybody know why it says "Permission denied" and "Can't locate 
Net/Server/Proto/UNIX.pm"?

The file is there

-rw-r--r--  1 root  wheel  5323 May  5  2014 
/usr/local/lib/perl5/site_perl/Net/Server/Proto/UNIX.pm

I see this problem only on one of all our mailservers. All was installed 
and configured the same way so I can't find a difference.
