 collide with Macports-installed ports/stuff.

 you know, you simply can't be sure it doesn't collide.

 Almost all compilers will search first for headers and libraries in
 /usr/local, and you simply can't stop them from doing that.

 At the very least, when you're plugging away at build errors, you can move
 /usr/local/* out of the way, eg

 {{{
 sudo mv /usr/local/include /usr/local/incude-disabled
 sudo mv /usr/local/lib /usr/local/lib-disabled
 }}}

 and then they won't be picked up against your will.
