OK.  emerge -1vpt sys-power/upower-pm-utils gives me:

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

    Calculating dependencies  ... done!

    Total: 5 packages (5 new), Size of downloads: 6,513 kB
    Conflict: 2 blocks (2 unsatisfied)

.  Taking a hint from the emerge man page, and adding --update, I get:

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

    Calculating dependencies  ... done!
    [ebuild  N     ] sys-power/upower-pm-utils-0.9.23  USE="introspection -doc -ios" 416 kB
    [ebuild  N     ]  virtual/libgudev-208  USE="introspection -static-libs" ABI_X86="(64) (-32) (-x32)" 0 kB
    [ebuild     U  ]   sys-fs/udev-212-r1 [208] USE="acl firmware-loader gudev introspection kmod -doc (-selinux) -static-libs (-openrc%*)" ABI_X86="(64) (-32) (-x32)" 2,660 kB

    Total: 5 packages (3 upgrades, 2 new), Size of downloads: 6,110 kB

, which seems like what I wanted in the first place.  

Then again, I call

   emerge -1vpuND --color y --tree sys-power/upower-pm-utils 2>&1 | less -F

, things go pear shaped again, with:

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

    Calculating dependencies  .... ............. .. .... .............. .... done!

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

    dev-lang/perl:0

      (dev-lang/perl-5.16.3::gentoo, ebuild scheduled for merge) pulled in by
        >=dev-lang/perl-5.16 required by (dev-perl/XML-Parser-2.410.0::gentoo, installed)

      (dev-lang/perl-5.12.4-r1::gentoo, installed) pulled in by
        dev-lang/perl:0/0= required by (net-print/cups-filters-1.0.53::gentoo, installed)

      (app-text/poppler-0.26.1::gentoo, ebuild scheduled for merge) pulled in by
        (no parents that aren't satisfied by other packages in this slot)


What the heck is going on, when a package management system can't even
make a decision on which version of perl to use, and stick to that
decision?  And it can only be described as a bug, that the gobbledegook
"(no parents that aren't satisfied by other packages in this slot)"
passes for a supposedly informative message.

Anyhow, thanks indeed for the help.  Maybe, someday in the distant
future, I'll succeed in updating my Gentoo system after all.

Have a great evening!
