Check that /usr/local/Trolltech/Qt-4.5.0-tp/bin/qmake exist and if so append 
the output of:

qmake -query QT_INSTALL_DATA QT_INSTALL_LIBS QT_INSTALL_HEADERS 
QT_INSTALL_DEMOS QT_INSTALL_EXAMPLES QT_INSTALL_CONFIGURATION 
QT_INSTALL_TRANSLATIONS QT_INSTALL_PLUGINS QT_INSTALL_BINS QT_INSTALL_DOCS 
QT_INSTALL_PREFIX

All in one line. That should help me pinpoint why you get that message.
