qttranslations fails to install

When i was following the QT5 build instructions located at http://qt-project.org/wiki/Building-Qt-5-from-Git i found that the build does fails every time during the install phase because qttranslations is searching for lrelease in qtbase/bin instead of qttools/bin. This should not be happening.

as for when the error occurs, this is when i run the "make install" after building the software.
Note 1: Init-repository was ran with the option "—no-webkit"
Note 2: the configuration script was ran with the following line:
./configure -prefix-install -prefix /opt/qt5 -nomake tests -nomake translations -opensource -opengl
