Thanks Renat, I am still struggling to understand why mysql is being
dragged in.  It seems that x11-libs/qt-sql-4.5.2 is already installed
with the sqlite flag:
=================================
 Installed versions:  4.5.2(4)(12:30:57 10/10/09)(iconv qt3support
sqlite -debug -firebird -mysql -odbc -pch -postgres)
=================================

I've added -mysql in /etc/portage/package.use for x11-libs/qt-sql but
it makes no difference.  Then I added mysql and all this mess comes
up:
=================================
# emerge -upDv world

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

Calculating dependencies... done!

!!! Multiple package instances within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:

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.


emerge: there are no ebuilds built with USE flags to satisfy
">=dev-python/PyQt4-4.5[dbus,sql,svg,webkit,X]".
!!! One of the following packages is required to complete your request:
- dev-python/PyQt4-4.5.4-r4 (Change USE: +sql +webkit)
(dependency required by "kde-base/pykde4-4.3.1" [ebuild])
(dependency required by "kde-base/plasma-workspace-4.3.1" [ebuild])
(dependency required by "kde-base/kdebase-meta-4.3.1" [ebuild])
(dependency required by "world" [argument])
=================================

It seems to me that it may be easier to just unmerge krfb and forget
about it, but there must be a more elegant solution to this?
