It is indeed.  This is the symbolic link.  If you cd to /usr/X11R6, you'll
find that you're effectively in the /usr/X11R6.3 directory, although it
appears to be called something else.

Try jmacs as the actual command name - that's what I use.  I'm not quite
sure how it's all supposed to hang together, but it appears to work.

Try typing startx in your home directory (cd ~ to get to it).  If you then
get 'startx: Command not found', as I suspect you will then this is
because /usr/X11R6/bin needs to be added to you PATH variable.  To do this
you need to edit a file depending on which shell you are using.  If you're
using bash, then it's .profile that you want.  If you're using csh, then
it's .cshrc.  (Both in your home directory.)  There should be a line
specifying the PATH variable.  Just add /usr/X11R6/bin to that line,
noting that each part of the PATH variable is separate by a :

Then logout and log back in again to force the changes to be read in, and
you should be okay.  (Hopefully!)

Hope this helps,

PS - If this doesn't work then you'd probably be best reinstalling all the
X sets.
