Thanks for pointing to that link, it was very useful, as was some of
the discussion I was able to access around it.

While bringing my concerns to the mailing list and responding to other
peoples responses I had this nagging feeling that I was missing something.
I can see from the core devs that individually and collectively you have a
lot of experience to draw upon.  After reading through some of the messages
on the dev list around the linked post, I feel a lot more satisfied that 
if the
potential problems that I have expressed appear, then a solution will be 
found.

Dependency management is certainly a hard problem and all of the package 
managers
that I have used have their issues.  Who knows, the Rackety solution, by 
not trying
to emulate and tweak a previous model, may come up with something 
completely novel.



Best wishes
