I suggest the following changes:

	s/gnu/GNU/
	s/patch/`patch'/

Also the message is not very clear. 
Note that "synopsis" means "summary", not "command-line argument syntax".
Also I think "does" should be "does not"?
And the message does not cover all the possible causes of failure; another
reason that this code might fail is that `patch' might not be installed at
all. 

Something like the following might be clearer:

	*** Unable to use `patch' system command.
	Make sure that you have `patch' installed and in your PATH.
	If you already have a version of `patch' installed, and it
	is not working, then try using the GNU version of patch instead.
