Yes it is. Because Qt/E is an integral part of the Zaurus you can link GPL 
code against it. You can't link GPL code against the ordinary commercial 
edition of Qt because it isn't an integral part of the system - that's a 
condition of the GPL.

It's dangerous to make assumptions about what a user may or may not already 
have installed.

The patch is still in my in-tray.

You need to look inside build.py and change how the features file is 
generated, or temporarily hack qglobal.h to pretend that fewer classes are 
implemented.

That's a bug in my internal build system which should be fixed in tonight's 
snapshot.

As you may have guessed, support for the Zaurus (and Qt/Embedded generally) is 
a long way down my list of priorities. This is simply because I get no 
benefit at all from supporting it.
