Hiya,

KDE CVS contains a module "qt-copy" which currently contains a
hopefully compilable version of Qt from 15 Dec. 1999. 

This is the recommended version to use together with KDE CVS until
further notice.

If you wish to make use of another version make sure you don't create
code which depends on features not present in the version from 15 Dec.
1999. (Or do some magic with kdelibs/qk)

Cheers,
Waldo
