I'm getting this error when I try to install BrowseUnit v. 3 in a fresh
3.7a-5763 image: "MessageNotUnderstood: BrowseUnit class>>browse".   The
problem seems to be in the SAR's postscript:
	StringHolder new acceptContents: (self memberNamed:
'install/readme.txt') contents;
		 openLabel: 'README'.
	^ BrowseUnit browse

I didn't see any dependencies listed for the BrowseUnit package, so I
haven't installed the RefactoringBrowser or Whisker, etc..   

Thanks,
Brent
