I'm getting numerous errors when I try to create the RInside qtdensity example.
This is my first experience with Qt so I suspect there's some simple

^~~~~~~~~
/usr/local/Qt-5.0.2/include/QtWidgets/qabstractspinbox.h:55:7: note: forward

class QLineEdit;

qtdensity.cpp:38:14: error: no matching member function for call to 'connect'
QObject::connect(cmdEntry, SIGNAL(textEdited(QString)), this,...
~~~~~~~~~^~~~~~~
/usr/local/Qt-5.0.2/include/QtCore/qobject.h:199:36: note: candidate function
not viable: cannot convert argument of incomplete type 'QLineEdit *' to
'const QObject *'

---
The fatal errors occur when processing Qt header files, so perhaps I
have a problem with my Qt installation.
