Did you source the rc.conf files?

I am used to using csh/tcsh which uses the source command.  I 
am not sure I remember it for sh, but it might be just '.' followed
by the file name.

Sourcing the file sucks it in and makes all the variable settings
available to the current shell.    You need to do some handbook and
shell documentation reading and example studying.   There are lots
of things on the system that do this and that make good examples
to emulate.    I am not a shell programmer per se, but I manage to
get by through grabbing chunks of things that already work on the
system ad modifying they for my current use.   I think many people
learn that way.

Things like setenv, set, source and such.   rc.d startup scripts, rc.conf.

What does your rc.conf look like?
Boot up with it and then take a look at the values.
make a startup script for whatever it is - probably the install
already put one in /usr/local/etc/rc.d/  
and in that startup script, source the /etc/rc.conf file.
