 When liblzma tries to uninstall itself, it is prevented from doing so in
 the following way:

 {{{
 --->  Unable to uninstall liblzma @5.0.3_0, the following ports depend on
 it:
 --->    kdelibs4 @4.8.3_2
 Error: org.macports.uninstall for port liblzma returned: Please uninstall
 the ports that depend on liblzma first.
 Please see the log file for port liblzma for details:

 }}}

 I'm aware that liblzma has been superseded by xz.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

 What's weird is that port info kdelibs4 produces:

 {{{
 kdelibs4 @4.8.3, Revision 2 (kde, kde4)

 }}}

 … which indicates that the dependency is on xz, no mention of liblzma! And
 I don't have any older installed versions, port installed kdelibs4:

 {{{
 The following ports are currently installed:
   kdelibs4 @4.8.3_2 (active)
 }}}

 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)!
