This works nicely:

	OSProcess thisOSProcess waitForCommand: '/bin/ls'.

so the plugin is ok, but this doesn't:

	OSProcess thisOSProcess waitForCommandOutput: '/bin/ls'.

as in UnixProcess>>waitForCommandOutput	the line
       					
	^ (PipeableOSProcess command: aCommandString) output

gives a

	MessageNotUnderstood: command:  

which is quite understandable as PipeableOSProcess doesn't exist anywhere.
What did I miss?
