Thanks! Croquet is started with a shell script not directly. Here it is:
------------------------------------------------------------------------
#!/bin/sh

case $# in
        0)      : find the latest Croquet image
                set 0 Croquet.*.image
                while [ $# != 1 ] ; do shift ; done
esac

IMAGE=${1}
DIR=`dirname $0`
EXE="$DIR/bin/i686-pc-linux-gnu"

# make source link if necessary
if [ ! -r $DIR/CroquetV1.sources ] ; then
        ln -s $DIR/bin/CroquetV1.sources $DIR/CroquetV1.sources
fi

# make libGL.so link if necessary
if [ ! -x /usr/lib/libGL.so -a -x /usr/lib/libGL.so.1 ] ; then
        if [ ! -x  "$EXE/libGL.so" ] ; then
                echo Creating libGL.so symlink in $EXE
                ln -sf /usr/lib/libGL.so.1 "$EXE/libGL.so"
        fi
fi           
-----------------------------------------------------------

Notice they are trying like heck to insure that the libGL files are
found as it has been a huge problem with Squeak, the underlying language
Croquet uses. Should I add those statements to here?? Ric
