Hi, Simon:


	  Thanks for this.  I have more questions:

	  Please excuse my ignorance, but I don't understand this.  I 
previously tried "PATH=/bin:/sbin:/user/bin:/user/sbin:/system/Library/ 
export PATH", recommended on a page associated with support.apple.com, 
as mentioned below.  That did not seem to work for me.


	  How is this different?  What did I do wrong before that this would 
fix?  [Or feel free to ignore this question:  My immediate problem seems 
to be fixed, and I'm not eager to do more experimentation with this now 
;-]

	  If I set this in RStudio, will it affect what I do in "Terminal" on 
my Mac and vice versa?


	  This looks like a potentially similar thing to do from what I did. 
Is the effect of this different?  If so, how? [Again, please feel free 
to ignore this question.  I'm not eager to practice my "do-it-myself 
lobotomy" skills ;-]


	  Thanks,

I did "env" to get the current path, than appended ":/opt/gfortran/bin" to that and executed the revised "PATH=...:/opt/gfortran/bin export PATH".  However, when I checked with "env" again, the change was not displayed.  I rebooted with the same result.
