I think I am sort of seeing what is going on here. perl -V is using  
the macports version for some reason.   would think that `perl` needs  
to continue to use the OS X perl, and that I would need to call out  
the /opt/local/bin/perl when I want to use the MacPorts one.

I came to this conclusion since when making a port, one of the main  
things the port does, is read in files and do a find and replace on  
the built in perl and stuff in /opt/local/bin/perl.

If that is the case, then it has to be my .bashrc file that is messing  
with the proper behavior.

I have the usual
export PATH="$PATH:$HOME/bin"

And I added in
# For MacPorts
export PATH=/opt/local/bin:/opt/local/sbin:$PATH
export DISPLAY=:0.0
export EDITOR=/usr/bin/mate

I had to ditch the pre-installed .profile since it did not work for  
me. Maybe I should have referenced it from this file.  How do I tell  
the shell to use a certain order on where perl is located, or is that  
the wrong way to solve this?

Also, is there any way for EDITOR to be dynamic, so that when I am on  
the actual machine I want to use mate as my editor, but if I am over  
ssh, I want to use a terminal based editor.  Is that just a matter of  
wrapping the default in a condition that checks where I am at?
