        daip at nrao.edu is better - and reaches me just as fast (and
others in case I am away)

      Installing as root causes many problems - install as yourself or
some other ordinary account.

       This states that there is no /usr/include/X11 directory on your
system.  Usually there is something like a link to the current version
of X e.g.       X11 -> ../X11R6/include/X11/
on my system.  You will have to be root to make this link.  Then the
XAS may be remade eith by rerunning install.pl or by

cd $AIPS_ROOT
source LOGIN.CSH   (or . LOGIN.SH)
$CDTST
cd $YSERV/XAS
make

       Note the reference to 32DEC02 - you must have had that
installed and then inherited the reference from ~/.AIPSRC.  Edit the
$SYSLOCAL/CCOPTS.SH file to change 02 to 03 (and also ~/.AIPSRC).

Do these two edits, fix the X11 link file, then re-run install.pl.
