Does the -xshm option need to be specified if xshm is compiled in?  Running squeak -version shows:
i686-pc-linux-gnu 3.1a-4164 #1 XShm Fri Jul 27 10:34:57 EDT 2001 gcc 2.95.2
Linux double 2.4.5 #4 SMP Mon Jul 9 09:57:00 EDT 2001 i686 unknown
default plugin location: /usr/local/lib/squeak/3.1a-4164/*.so


	So must I still specify this option?

	Thanks!
