Install Error: The current directory must be set to the ITT directory

[caroline]

How do I fix this? I was able to build but failed gmake install

gmake[1]: [install_flat_headers] Error 1 (ignored)
install -m 644 -p /users/qt-everywhere-opensource-src-4.8.1/src/corelib/kernel/qsharedmemory.h /usr/local/Trolltech/Qt-4.8.1/include/Qt/
 
    The current directory must be set to the ITT directory.
    Change the default to the ITT directory and re-run
    this script.
