Comment (by kenneth.f.cunningham@…):

 OK - I realize now that the qt4-mac portfile is incredibly complicated. I
 suspect that the underlying issue could be that the mkspec chosen for this
 platform  doesn't take into account the libc++ modification done to
 10.6.8. It chooses macx-g++ as the mkspec, and (deference here to someone
 who knows better) might better be choosing macx-clang-libc++.

 To compile it as it is, I did
 {{{
 "sudo port install qt4-mac configure.sdkroot="/"
 }}}
 to get started, then manually altered a couple of Makefiles to correct
 errors
 {{{
 in src/corelib/Makefile

 add -lobjc to
 LFLAGS        = -L/opt/local/lib -lobjc -Wl,-headerpad_max_install_names
 -stdlib=libc++ -Wl,-syslibroot,/ -arch x86_64 -Wl,-syslibroot,/
 -single_module -dynamiclib -compatibility_version      4.8
 -current_version    4.8.7 -install_name
 /opt/local/libexec/qt4/Library/Frameworks/QtCore.framework/Versions/4/QtCore
 -Xarch_x86_64 -mmacosx-version-min=10.6 -Xarch_x86_64 -mmacosx-version-
 min=10.6
 }}}
 and
 {{{
 in src/plugins/bearer/corewlan/Makefile

 add -framework Security
 LIBS          = $(SUBLIBS) -F/System/Library/Frameworks
 -F/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_aqua_qt4-mac/qt4-mac/work

 }}}

 I believe that was all that was needed.
