So it was. Ok, I have made this conditional on the Qt version; if you  
build with an older Qt version, the debugger won't be available.

Does the presence of

   QT += scripttools

in the .pro file cause a problem if the QtScriptTools module isn't  
available? I guess it should be possible to conditionalize this also,  
if necessary, but I wasn't sure offhand what's the easiest way in  
qmake...
