The silly installer just has a giant binary blob at the end that is simply a .tar.bz2 file. Put graal4setup into the directory where you want to install Graal, then run this from that directory:

grep --text 'export data_size' graal4setup | grep --only-matching '[0-9]\+' | xargs --replace tail --bytes={} graal4setup | tar xj ; printf >run-graal '#!/bin/sh\ncd "'"`pwd`"'"\nLD_LIBRARY_PATH=. ./graal' ; chmod a+x run-graal ; mkdir license ; cp sig.graal sig.license license.graal license/

If you have the required libraries installed, you should be able to run run-graal to start Graal.

Edit: The RC binary from 2004 still runs for me. No idea how usable it is, lacking a proper staff account.
