Seems to be ...

AFAIK ubuntu has some qt-jambi packages, I have used jambi-designer from 
there, but some of them are buggy ( and as I know ubuntu, they will stay 
buggy forever :-] ).

But when I tried to backport that packages to etch, I wasn't successfull. I 
thing that ubuntu has different configure parameters of qt4 for qtjambi 
compatibility.

I understand your fight, native qt-jambi binary distribution is little 
unfriendly for linux ( I mean shell scripts wrapping designer etc..., they 
are looking for some stuff in 'pwd' and so they are absolutely unusable as 
system libraries).

But - original binary qtjambi distribution has a big benefit - you should run 
your application on any computer if you bundle qt jars together with your 
app, because that jars contains native c++ qt libs too. I know that it 
is 'breaking' the package managment idea on most linux distros and using much 
more disk/ram space, but sometimes it should be very useful ( mostly when you 
want to run your apps on mixed environment [windows/linux] ).

Yes. But it was a hard job on debian, I wasn't successful some time ago ( I 
spent about 1 day with it, configure, make, wait_long_time, not works, 
delete, reconfigure, rebuild ... )
