[Zope] RPCAuth again

[David Cake]

	OK, I asked previously about installing RPCAuth on Debian. I 
got no useful responses (thanks to Tres Seaver for passing my message 
on to the author, but they didn't get back to me). There is basically 
no documentation on this product, couldn't get it to install on 
either zope 2.7 on Debian (apparently stops entire zope instance from 
working) or Mac OS X (just never shows up - its in 
/Applications/Plone2/Sites/Default/Products/ along with other 
products, but can't see any evidence Zope knows its there).
	So, anyone managed to install this product, or know how to 
debug installation problems of this kind?
	I'm having a very mixed experience with Zope/Plone - I either 
get a lot done in a short time, or things don't work and I get 
stopped dead, with very little documentation or help as to how to 
proceed.
	Regards
