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. You may want to try a larger value of
the --backtrack option, such as --backtrack=30, in order to see if
that will solve this conflict automatically.

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


Adding --backtrack gives this:
===================================
# emerge -uaDv --backtrack=30 world

Hmm ... no I do not have any emul-linux packages in my world file:

# less /var/lib/portage/world | grep emul-linux

Thanks, I saw the warning about conflicting slots and wanted to make sure I
won't cause any (significant) breakage. Do you mean that I should unmerge the
previous versions (20110129)?

Problem solved - I uninstalled app-emulation/emul-linux-x86-xlibs-20110129,
then emerged app-emulation/emul-linux-x86-xlibs and after I unmasked app-
emulation/emul-linux-x86-motif-20110722, portage took care of the remaining.

Thanks for the pointer!
