It is.

, put a shebang in; #!/usr/bin/env tclsh

Here's the current script's starting lines:

#!/bin/sh
# Run tcl from users PATH \
exec tclsh "$0" "$@"

Here's the rc script I'm working on.

. /etc/rc.subr

load_rc_config pads_agent

#set defaults
pads_agent_enable=${pads_agent_enable:-"NO"}
pads_agent_conf=${pads_agent_conf:-"/usr/local/etc/sguil-sensor/pads_agent.conf"}
pads_agent_flags="${pads_agent_flags}:-"-D -c ${pads_agent_conf}"

name="pads_agent"
rcvar=pads_agent_enable

command="/usr/local/bin/sguil-sensor/pads_agent.tcl"
command_interpreter="tclsh"
command_args=${pads_agent_flags}

run_rc_command "$@"

Here's the error I'm getting when I run start:

/usr/local/etc/rc.d/pads_agent: WARNING: $command_interpreter tclsh != 
/bin/sh
Starting pads_agent.
/usr/local/etc/rc.d/pads_agent: WARNING: $command_interpreter tclsh != 
/bin/sh
/usr/local/etc/rc.d/pads_agent: unknown directive 
'/usr/local/bin/sguil-sensor/pads_agent.tcl'.
Usage: /usr/local/etc/rc.d/pads_agent 
[fast|force|one|quiet](start|stop|restart|rcvar|status|poll)
/usr/local/etc/rc.d/pads_agent: WARNING: failed to start pads_agent

I tried changing the interpreter to "/bin/sh" but I got the same error.

Here's the perms on the script:

# ls -lsa /usr/local/bin/sguil-sensor/pads_agent.tcl
12 -r-xr-xr-x  1 root  wheel  11662 Dec  6 18:31
