Set LD_LIBRARY_PATH to include the relevant directory.  Here's the script I
use at Teleplace, where the script is root/bin/squeak and the so's are in
root/lib/squeak/3.9-7.  You can tailor to suit.

#!/bin/sh
BIN=`/usr/bin/dirname "$0"`/../lib/squeak/3.9-7
# At least on linux LD_LIBRARY_PATH's components must be absolute path names
case "$BIN" in
/*) PLUGINS="$BIN";;
*) PLUGINS="`pwd`/$BIN"
esac
# prepending is less flexible but safer because it ensures we find the
plugins
# in the same directory as the VM.
LD_LIBRARY_PATH=$PLUGINS${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH} exec
"$BIN/squeak" "$@"
