Thanks, Portage has resolved conflicts, I'm on 4.5.2 now. It seems like qt3support
flags deletion doesn't work for me. Now, after upgrading, I have tried to comment out
those flags in package.use and got conflicts (below).

===========================================

emerge -pvDuN world

These are the packages that would be merged, in order:

It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously. If such a conflict exists in the
dependencies of two different packages, then those packages can not be
installed simultaneously.

For more information, see MASKED PACKAGES section in the emerge man page
or refer to the Gentoo Handbook.
