Comment (by kencu):

 this kind of thing is why we insist on clean buildbot-built software to
 distribute.(eg why we can’t use someone’s gcc build to distribute via
 macports).

 by default, all compilers are configured to search /usr/local for headers
 and libs.

 the only compilers that do not do this, I believe, are macports-built gcc
 compilers, due to this:

 https://github.com/macports/macports-
 ports/blob/8ca160c32e0864ac8ce770389f206c30516d2fff/lang/gcc14/Portfile#L139

 and I’d have to check to make sure if that applies to every single
 macports gcc compiler
