Here's the output:

But doesn't --prune just remove all but the most recent installation
of a given package?

While on the subject, I ran a pretend on revdep-rebuild, and it's
complaining about some broken libraries in GCC...

langevin etc # revdep-rebuild -p -v
Configuring search environment for revdep-rebuild

Environment mismatch from previous run, deleting temporary files...

Checking reverse dependencies...

Packages containing binaries and libraries broken by a package update
will be emerged.

Collecting system binaries and libraries... done.
  (/root/.revdep-rebuild.1_files)

Collecting complete LD_LIBRARY_PATH... done.
  (/root/.revdep-rebuild.2_ldpath)

Checking dynamic linking consistency...
  broken /usr/lib/gcc/i686-pc-linux-gnu/4.1.2/libgcjawt.la (requires
/usr/lib/lib-gnu-java-awt-peer-gtk.la)
  broken /usr/lib/gcc/i686-pc-linux-gnu/4.1.2/libgij.la (requires
/usr/lib/libgcj.la)
 done.
  (/root/.revdep-rebuild.3_rebuild)

Assigning files to ebuilds... done.
  (/root/.revdep-rebuild.4_ebuilds)

Evaluating package order... done.
  (/root/.revdep-rebuild.5_order)

All prepared. Starting rebuild...
emerge --oneshot -p -v =sys-devel/gcc-4.1.2

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

Calculating dependencies... done!
[ebuild   R   ] sys-devel/gcc-4.1.2  USE="fortran gcj gtk mudflap nls

(-multilib) -multislot (-n32) (-n64) -nocxx -objc -objc++ -objc-gc
-test -vanilla" 0 kB

Total: 1 package (1 reinstall), Size of downloads: 0 kB
Now you can remove -p (or --pretend) from arguments and re-run revdep-rebuild.

I'm a little uneasy doing a --oneshot emerge of GCC when I just
recompiled my system twice...  I'm not sure how that will affect my
GCC upgrades in the future.  I only upgraded a minor version of GCC,
too.  Any thoughts?
