Very easy.  Make Postfix obey the port path, when obtaining header
files and linking components.  It should get everything from the
system location, or it should get everything from the default
location.  The most likely scenario is that the include path is
not being overridden, even when the library path is.  This is
most likely due to a bug in the GNU configure script.  The best
way around those bugs is "do not use GNU configure".

FWIW: this confirms that it's a Postfix problem.
