Hi Lemmyslender
It amazes me how easily one can forget the steps taken to get to a point of getting things to work :-( I try to keep notes on when and how I add to a dev environment. But I don't always remeber that I wrote them down.
I have now updated the wiki to describe fully the installation of additional tools under Scratchbox.

As to patching from diffs, the best thing l I can do is point you to the man page for 'patch', thankfully this is included in the Scratchbox environment.
