Very strange but if Qt is build at first machine and copied to second, even after having qt.conf with new path as a prefix: Prefix=/Users/user/My/Path/To/Qt, For some reason it still looks for UIC at old path (where it got build)

If I do qmake -query, it returns the new paths,but qmake is still using the initial path for 'uic'(which is old one) though it picks correct new path for moc.

Further debugging I see for some reason QT_TOOL.uic.binary is still pointing to old path. Manually editing the correct path in "qtbase/mkspecs/modules/qt_tool_uic.pri" seems the only way to get it work.
