This port requireat least s version 1.41 of the Qt library.
There will be an error reported by configure, if only an earlier
version is found, but no automatic port dependency exists (i.e.
the x11-toolkits/qt141 port has to be manually built and installed).
There may still be a problem with a missing -lXext in the kdesupport
port. This will be taken care of during the next few days, if the
problem still exists ...
Recompile all your applications!
Only the minor revision of the shared libraries changed, but
they are not really upward compatible with those from Beta2!
The use of --x-inc and --x-lib to pass in multiple directories is a hack,
and should be replaced by a more robust approach. It works, but relies on
implementation details of the configure script.
