Looks like your argument to "root" is the wrong path. It points into 
your build directory, but shouldn't it refer to your source folder, 
where "res/images/red_arrow.png" can actually be found?

Usually you would name your Moc results something like "moc_*.cpp". This 
setup might work for you, as long as no conflicting CPP file 
"deviationAreaWidget.cpp" is in "uiDirector/src", but it will confuse 
other users...you might want to change this and rename the files.

I think it's the same error as before , but now for the $LIBS variable. 
Your linker messages indicate that libqtmain and libQtGui* don't get 
linked. Ensure for all the variables you set within in your framework 
(CPPPATH, LIBPATH, LIBS,...), that
they get properly merged with the values coming from definitions within 
the SConstruct/SConscript files.
This is required to make your extension work together with any SCons 
Tool, not only Qt4.

Dirk
