So according to you a dependencies should never install their headers in the 
include root when that root is not / or /usr/local?

Or is the QWE buildsystem unreliable because it doesn't reorder the -I options 
(assuming that the issue in this thread can indeed be prevented by constructing 
the header dir search path with the "system" locations last)?

FWIW, I do set the CPATH env. variable to /opt/local/include.

Here's what happens when I remove the offending -I/opt/local/include:
