Comment(by michaelld@…):

 Disabling pre-xompiled headers doesn't do it; CLANG just ignores the CPATH
 and LIBRARY_PATH variables, as has been pointed out elsewhere (e.g., <
 http://lists.macosforge.org/pipermail/macports-dev/2011-August/015543.html
 >).  One of the reasons I moved to using CPATH (etc) is that QMake does
 not follow "reasonable" ordering for headers -- should generally be: local
 (to project), non-local (but not system), compiler, system.  When I get
 time again (in a few weeks), I'll see if QMake 4.7.4 does ordering better.
 In the mean time, don't use CLANG as the compiler for qt4-mac.
