Q:

Where does apt-get install libqt4?

I've been searching for literally hours and I cannot figure out where for the life of me libqt4 is installed by apt-get.
I installed:
libqt4-dev
libqt4-core
libqt4-gui
libqt4-xml
libqt4-opengl

Next, I installed QtCreator 2.5.2 with the binary install file downloaded from qt-project.org because the QtCreator available in the Ubuntu repos is only 2.4.
QtCreator has to be able to find qt libraries and qmake on my system, but I can't even find them.  Does anyone know where the $*(^#$(&^# apt-get installs them?

A:

You can find out where files are installed with dpkg:
dpkg --listfiles libqt4-dev
