The missing piece is the OSProcessPlugin, which is an optional plugin
that permits the Squeak virtual machine to gain access to various
operating system functions.
The plugin is normally distributed with the Unix VM, so OSProcess and
CommandShell work fine on Unix and Linux systems. The plugin is also
available for the Mac OS X VM, but I don't think that it is distributed
with the Mac VM. John McIntosh makes it available on his web site
ftp.smalltalkconsulting.com, although I don't know exactly how to go
about getting it and installing it on a Mac (perhaps someone else can
explain). On Windows, the OSProcessPlugin is not completely implemented,
so CommandShell will not work for you on Windows.
