Until recently an IDE built with  make bigide  recompiled at least some 
packages when told to build the first project. This was irrespective of 
whether I was patching in e.g. lazsvnpkg.

It's apparently been fixed, but I'll keep an eye on it.

OK. So going back to my original query: if I want to add something like 
lazsvnpkg for the initial build I've got to patch it in myself.
