Here are two things to try: 1) Run this command: java -\? and check the resulting help message to make sure that -cp is an accepted alias for the -classpath option. If it's not listed, you can try editing the 'install_visad' script and changing the line near the bottom of the script from: if [ -f $DISTDIR/visad.jar ]; then CPARG="-cp $DISTDIR/visad.jar" fi to: if [ -f $DISTDIR/visad.jar ]; then CPARG="-classpath $DISTDIR/visad.jar" fi If that change works, let me know and I'll make the appropriate fix in the distributed copy of 'install_visad'. 2) If (1) doesn't work, run the following commands: script java -version java -\? sh -xv ./install_visad ^D If the ^D doesn't work, you may need to type 'exit' to get out of the 'script' session. This will produce a verbose 'typescript' file recording all terminal input/output while 'install_visad' is running. Mail that 'typescript' to me (dglo@xxxxxxxxxxxxx) and I'll see if I can figure out what's going wrong.
