Hardcoded library paths in osx installation

I'm testing qt5beta2 snapshots from http://origin.releases.qt-project.org/digia/5.0.0_beta2
Most Qt5 frameworks when installed gets their library path patched correctly, example:

Lapidus:lib fab$ otool -L QtGui.framework/QtGui
QtGui.framework/QtGui:
/Users/fab/Qt5.0.0beta2/5.0.0-beta2/clang_64/lib/QtGui.framework/Versions/5/QtGui (compatibility version 5.0.0, current version 5.0.0)
/Users/fab/Qt5.0.0beta2/5.0.0-beta2/clang_64/lib/QtCore.framework/Versions/5/QtCore (compatibility version 5.0.0, current version 5.0.0)
/System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa (compatibility version 1.0.0, current version 17.0.0)
/usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 1.2.5)
/System/Library/Frameworks/OpenGL.framework/Versions/A/OpenGL (compatibility version 1.0.0, current version 1.0.0)
/System/Library/Frameworks/AGL.framework/Versions/A/AGL (compatibility version 1.0.0, current version 1.0.0)
/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 52.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 159.1.0)
/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 635.19.0)

The patching doesn't work properly at least on QtSvg framework, where we can still find the hardcoded compilation path of the build machine:

Lapidus:lib fab$ otool -L QtSvg.framework/QtSvg
QtSvg.framework/QtSvg:
