Entirely true, but this will result in NEEDS being in /usr/pkg more than
/usr/lib, so it should be reasonably easy for the analyzer to understand
this.

But your note brings up another point that is perhaps surprising to
those used to Linux: it's relatively normal for people/groups at various
scales to tweak some config variables and do a build of many packages.
I have the impression that in Linux there is no convenient bulk build
mechanism and it's very odd for someone to say rebuild all of Debian
with different compiler flags.
