Oh.  This is odd, because I appear only to have a /usr/X11R6.3 directory.
Where did you get your sets from?  Anyway, that explains the next point,
because I had expected there to be a /usr/X11R6.3 directory in the
instructions I gave.

> 2) When I cd to X11R6, it says something along the lines of file not found

Okay, in that case, do 	"rm /usr/X11R6"  then 
			"ln -s /usr/X116.1 /usr/X11R6"

This will then do what I had hoped the other command would do.

Err.  Are you *sure* you installed the set?  It should (I think) be in
/usr/local/bin - try looking there and see if you can see it.  (I'm
presuming that /usr/local/bin is in your $PATH ?)

Sorry about that.  The shell is the program that provides you with the
command prompt, accepts your commands and executes them.  There are
several different types of shell.  

You can determine which one you're using by typing 'ps'.  This will give
you a list of processes (programs)  that you're currently running.  One of
these will be a shell, called "bash", "tcsh", "csh", "sh" or "ksh" or
similar. 

I seem to remember that the default shell for root is csh, but I'm not
sure (I changed it to bash quite quickly).  In which case, you want to
look in .cshrc.

Hope this helps,
David.
