I think we most likely would have to drop support for this, especially 
if Trolltech would not support it for Qt (need to check that again, I 
can't recall the facts there)

KDE/FreeBSD packagers typically only support the last couple of 
revisions of an OS branch, and 5.4 (the current most-recent) uses 3.4.2

FreeBSD 5.4 has 3.4.2
FreeBSD 6.0 has 3.4.4

This is the important part at least for the K/F packaging team. We don't 
want to have to force people to upgrade their compiler suites, because 
there are almost 14000 applications/suites in our packages, and 
virtually all are made to build on the system compiler. We only 
maintain the KDE ports and a few others, and we can't enforce a 
compiler change on the maintainers of other parts of the ports system. 

It would be interesting to hear from some of the packagers from other 
non-linux systems to see what they think on this.
