I'm still working on the changes to kalyptus. I've added a '--qte' option, and 
the .cpp sources are now quite close to compiling as well as the java.

Koala is just the name for the KDE java bindings, so sorry that isn't needed.

I couldn't get automake/autoconf to work with Qt 2, so I've been using qmake 
to generate a Makefile to compile the .cpp sources. 

I've built Qt/E 2.3.4 now and got an example working, although the example app 
I tried wouldn't accept mouse clicks in the framebuffer emulator - I need to 
find out more about that.

Perhaps the best thing is to wait until I can get everything built and 
working. I haven't checked in the kalyptus changes for .cpp code generation 
fixes and '--qte' option. Assuming there aren't any major unexpected problems 
with linking, a hello world app should be working later today.

I'll send you the current kalyptus code via email as it's too large for the 
kdebindings list.
