      I had said earlier $SYSLOCAL which should be #1 above.  Your
absence of environment variables is because you have not set yourself
up as a full aips manager:
    cd $AIPS_ROOT
    source LOGIN.CSH      (or . LOGIN.SH if using bash)
    $CDTST
Then all logicals are known.

     This looks right.

     Sorry to double check - as I said some people do not know unix
all that well and mis-interpret words like echo and type

    This is the problem and suggests that 2.95.3 did not install properly.

No it is a compiler issue.

Are you running on a Pentium IV?  If so, the binary installation path
may be desirable.  We are going to convert it to use the Intel
compiler especially for PIVs and it will run faster than the GNU
compiler.  To do a binary install, 
    perl install.pl -n
where the -n tells it to do a binary installation.  You must have the
rsync port open in your firewall.

Maybe Wes will be around today to help on this -lg2c issue.
