I stand corrected, thank you. But then to complete answering a previous 
question, "Setup install" does not configure, does not build, and is far 
from "cabal install".

I see where you heard this, but it is a misrepresentation from cabal, 
and older cabal has always told a similar misrepresentation.

When "cabal build" succeeds, it always says:

(older) "registering <name>-<version>"
(newer) "In-place registering <name>-<version>"

That's what it says. But use ghc-pkg and other tests to verify that no 
registration whatsoever has happened.
