 Yes, we set $command_interpreter to "/usr/local/bin/ruby".

 None of those.
 
 Here's a simple way to reproduce the problem:
 
 ------------------------ cut here -------------------- "frog.rc"
 #!/bin/sh
 #
 # PROVIDE: frog
 # REQUIRE: LOGIN
 
 . /etc/rc.subr
 
 # description: frog daemon
 #
 
 name="frog"
 rcvar=$name
 command=/home/frog/frog
 command_interpreter=/usr/local/bin/perl-5.6.1
 
 load_rc_config $name
 run_rc_command "$1"
 
 ------------------------ cut here -------------------- "frog"
 #!/usr/bin/env perl-5.6.1
 
 print "Hello world!\n";
 
 sleep(1000);
 ------------------------ cut here --------------------
 
 No need to start the "frog" daemon, just run the RC script:
 
   $ ./frog.rc forcestatus
   ./frog.rc: WARNING: $command_interpreter /usr/local/bin/perl-5.6.1 != 
/usr/bin/env
   frog is not running.
