 Replying to [ticket:35321 william@…]:
 > When liblzma tries to uninstall itself, it is prevented from doing so in
 the following way:

 You can force the uninstallation of liblzma since it is no longer needed
 since xz now takes its place:

 {{{
 sudo port -f uninstall liblzma
 }}}

 > I'm aware that liblzma has been superseded by xz. Is the correct
 solution simply to make kdelibs4 depend on xz instead of liblzma?

 Yes, and that has already happened in r94904. The reason this upgrade did
 not go smoothly is that the revision of kdelibs4 (and other ports that
 depended on liblzma) was not also increased at the same time. The problem
 will go away the next time kdelibs4's version or revision is increased for
 any other reason. Or you could also force kdelibs4 to rebuild now, if it
 bothers you:

 {{{
 sudo port -n upgrade --force kdelibs4
 }}}

 > Incidentally, Macports is at version 2.1.2, and this bug is still
 present, but that has not yet appeared in trac, so I set it to 2.1.1
 (where I first saw the problem)!

 Thanks, I have added 2.1.2 to the list of versions.
