Is that really "threading-multi" vs. "threading-muli" (note missing "t") ??

Not sure how you get those, as I get only the ones it actually builds things

Yes, for one good reason... it's the only way to effectively separate
incompatible built binaries from each other.

Very true ;-)

Another good point :-)

Yes that's been a big pain for many people.

It would actually introduce a _large_ number of directory levels to get
something like that. There are many variations that can cause built binaries
to be incompatible and they would all have to be accounted for in such a

But to really answer your concerns you should try the new build+install
support. It answers all of your problems. See this post:
