The configure command is,

./configure -fast -no-dbus -release -commercial -force-debug-info -openssl -cups -nis -v -harfbuzz -nomake demos -nomake examples -optimized-qmake -prefix /usr/local/qt/5.0.0rpath

It doesnt seem to install the headers for MAC.

After commenting out the line "CONFIG -= qt_install_headers" from,
QtCommercial5.0.0/qt-everywhere-commercial-src-5.0.0/qtbase/mkspecs/features/qt_module.prf

,as shown below,

#mac frameworks
mac:!static:contains(QT_CONFIG, qt_framework) {
#QMAKE_FRAMEWORK_VERSION = 4.0
CONFIG += lib_bundle qt_no_framework_direct_includes qt_framework
CONFIG(release, debug|release) {
!debug_and_release|build_pass {
# CONFIG -= qt_install_headers #no need to install these as well
FRAMEWORK_HEADERS.version = Versions
FRAMEWORK_HEADERS.files = $$SYNCQT.HEADER_FILES $$SYNCQT.HEADER_CLASSES
FRAMEWORK_HEADERS.path = Headers
}
QMAKE_BUNDLE_DATA += FRAMEWORK_HEADERS
}
}

and then a make install seemed to install the QtCore libraries.
