 A few notes:
 
 Problem is not 100% reproducible. I expect this is depend on the order 
 that the link names are returned when looked up. On two different 
 systems:
 
 $ cat foo24.pl
 #! /usr/pkg/bin/perl5.24.0
 print "$^X\n"; # $EXECUTABLE_NAME in English
 
 $ cat foo.pl
 #! /usr/pkg/bin/perl
 print "$^X\n"; # $EXECUTABLE_NAME in English
 
 # ./foo.pl
 /usr/pkg/bin/perl
 # ./foo24.pl
 /usr/pkg/bin/perl5.24.0
 # ls -l /usr/pkg/bin/perl*
 -rwxr-xr-x  2 root  wheel  11103 Aug 11 10:30 /usr/pkg/bin/perl
 -rwxr-xr-x  2 root  wheel  11103 Aug 11 10:30 /usr/pkg/bin/perl5.24.0
 
 mail# ./foo.pl
 /usr/pkg/bin/perl5.24.0
 mail# ./foo24.pl
 /usr/pkg/bin/perl5.24.0
 mail# ls -l /usr/pkg/bin/perl*
 -rwxr-xr-x  2 root  wheel  11103 Oct 20 16:45 /usr/pkg/bin/perl
 -rwxr-xr-x  2 root  wheel  11103 Oct 20 16:45 /usr/pkg/bin/perl5.24.0
 
 On the machine exhibiting the problem, I ran through a few steps regarding 
 Patrick's option 3):
 
 mail# ps axww -p `cat /var/run/spamd.pid`
    PID TTY STAT    TIME COMMAND
 25312 ?   Ss   0:13.71 /usr/pkg/bin/perl5.24.0 -T -w /usr/pkg/bin/spamd -m 15 -x -u spamassassin -d -r /var/run/spamd.pid
 mail# . /etc/rc.subr
 mail# check_pidfile /var/run/spamd.pid /usr/pkg/bin/spamd
 mail# check_pidfile /var/run/spamd.pid /usr/pkg/bin/spamd /usr/pkg/bin/perl
 mail# check_pidfile /var/run/spamd.pid /usr/pkg/bin/spamd /usr/pkg/bin/perl5.24.0
 sh: WARNING: $command_interpreter /usr/pkg/bin/perl5.24.0 != /usr/pkg/bin/perl
 
 Patrick worked on his step 2) and has submitted a bug report and a 
 patch for spamd to spamassassin:
 
 https://bz.apache.org/SpamAssassin/show_bug.cgi?id=7295
 https://bz.apache.org/SpamAssassin/attachment.cgi?id=5377&action=view
 
 I've been using his patch in production for a while without problems
