I have installed some libs for qt，such as qt4-x11-free-dev , libqtcore-
dev ...etc.
but still get the following error messages:

//-----------------------------------------------------------------------------
Making all in qt
make[4]: Entering directory `/home/root/google-gadgets-for-
linux-0.11.1/build/ggadget/qt'
/usr/bin/moc4 ../../../ggadget/qt/qt_main_loop.h -o qt_main_loop.moc
/bin/bash: /usr/bin/moc4: No such file or directory
make[4]: *** [qt_main_loop.moc] Error 127
make[4]: Leaving directory `/home/root/google-gadgets-for-linux-0.11.1/
build/ggadget/qt'
//-----------------------------------------------------------------------------

Could anyone helps me? Is there any libs I have to install to fix the
problem? Thanks.

There are some exe in /usr/bin, such as qvfb, qtdemo, and qtconfig.
But still, can't find moc,moc4,and qmake.
