Comment(by michaelld@…):

 Yes, that would probably work; I had no idea 'software' was installed in
 that way & that 'location' was provided by port either.

 Before pursuing that path:  I'm going to check in a change to the qt4-*
 Portfiles shortly that, I think, fix this ticket and #25476.  These
 changes go back to using CPATH & such for all of the external-to-Qt
 includes & such (as before I started all of this), but in addition
 manually removes any -I/opt/local*/include from the CPATH for SQLITE and
 DBUS variables such that those paths no longer included in the (eventual)
 Makefile's C*FLAGS -- they are instead searched last (via the CPATH).
