    Yes you did and we have learned something I hope.  Does

         /data/AIPS/AIPS_ROOT/31DEC06/LINUX/LIBR/INTELCMP

contain the file libsvml.so?  It seems as if your system will accept
quotes in the xterm command.  That can always be tested by typing

     xterm -e 'echo $LD_LIBRARY_PATH ; sleep 15 '


If the library is present, this suggests perhaps that the
LD_LIBRARY_PATH is being defined for interactive logins but not for
non-interactive logins (which is what I think we get whan a script
forks an xterm).  Try putting an echo $LD_LIBRARY_PATH within the
quoted strings in the command.  (XASERVERS in $SYSLOCAL is used if
present when you do Inet processes and UNIXSERVERS is used when you
say tv=local).  The manual command above might test that.
