Problems building from source with -no-gui configure option

I'm trying to do a minimal build from source using qt-everywhere-opensource-src-4.8.1. All I need is Qt scripting and the state machines ie no GUI.
I configured an built using:

./configure -prefix=/my_dir \
-opensource \
-silent \
-no-qt3support \
-no-accessibility \
-no-multimedia \
-no-phonon \
-no-svg \
-no-nis \
-no-cups <<< "yes"
gmake -silent

The configure generated some warnings and errors:

Project ERROR: Package gstreamer-app-0.10 not found
Project WARNING: DEPLOYMENT support required. This project only works on Symbian and WinCE
Project WARNING: Qt Mobility Messaging disabled!
Project ERROR: The Symbian Vibration Example only works for the Symbian target!
Project WARNING: The Maemo Vibration Example only works for the maemo target!
Project MESSAGE: OpenGL support is not available.

gmake produced one errors too:
...
compiling main.cpp
compiling .moc/release-shared/moc_main.cpp
linking ../../../../plugins/script/libqtscriptdbus.so
/usr/bin/ld: cannot find -lQtGui
...

and when I install I get the same linking error on libqtscriptdbus.so.

So a couple of questions:
1. Can I have QtScript without QtGui?
2. Can I have QtScript without QtScriptDbus?
3. What does QtScriptDBus do?
4. Can I prevent the examples and docs being installed?
5. Any other suggestions to minimize the install when all I want is QtCore and QtScript?

Thanks,
Steve

PS I'm building this on a CentOS 6.2 machine.

Added after 5 minutes:

Duh!
I did, of course have the -no-gui option specified on the configure line which I omitted out in my original post.

No replies. That's disappointing.
However I solved my original problem, then I found I had to include the GUI just for QApplication and now I have a different problem.

First the solution.
I think the problem was that either the example or the demos or both need QtGui. When I added -nomake examples and -nomake demos to my configure line, I was able to build and install successfully.

I am trying to use QStateMachine and I discovered that I needed to make a QApplication variable so that I could force the events to get processed. QApplication appears to be in the QtGui library so I had to build it even though I am not using any Qt widgets or other GUI elements. That is unfortunate since increases the build time probably by a factor of 3.

I'll start a new thread to report my new problem.
