https://bugreports.qt-project.org/browse/QTBUG-26111

This bug appears to have made its way back to the builds for osx.
I am running mountain lion, and its reproducible by,

git clone git://gitorious.org/qt/qt5.git qt5
cd qt5
git checkout stable
cd qt5
perl init-repository
// I make the examples and the tests
./configure -developer-build -opensource
make -j 4

cd qtjsbackend
export= PATH=../qtbase/bin:$PATH
qmake // this points to to the right version when I query
make
make install

//Error 1
cp -f -R "/Users/michaelchung/Qt-5.1-Source/QtOsx/qt5/qtbase/lib/QtV8.framework" "/Users/michaelchung/Qt-5.1-Source/QtOsx/qt5/qtbase/lib/QtV8.framework"
cp: /Users/michaelchung/Qt-5.1-Source/QtOsx/qt5/qtbase/lib/QtV8.framework: No such file or directory
make[3]: [install_target] Error 1 (ignored)

cd ..
cd qtdeclarative
qmake
make
install

ld: framework not found QtV8
