Hi Bo,
   Thanks for the response. Hopefully I'm approaching this correct.

Basically running 'equery depends' up the stack of what it's telling
me it wants to take out, or on the package that depends on what it
wants to take out, until I get to something I recognize as an
application the user wants. Is this not the right way to look for why
this is happening?

For instance, this one is easy. --depclean wants to remove gnome-extra/at-spi:

gandalf ~ # equery depends gnome-extra/at-spi
[ Searching for packages depending on gnome-extra/at-spi... ]
gnome-base/gnome-2.16.2

The next is less obvious but the result is direct. --depclean wants to
remove dev-scheme/guile:

gandalf ~ # equery depends dev-scheme/guile
[ Searching for packages depending on dev-scheme/guile... ]
gnome-extra/gnome-games-2.16.2
gandalf ~ #

Finally this one takes a few steps to get to the top. --depclean wants
to remove media-libs/jasper:

gandalf ~ # equery depends media-libs/jasper
[ Searching for packages depending on media-libs/jasper... ]
media-gfx/imagemagick-6.3.0.5
media-libs/netpbm-10.37.0
gandalf ~ # equery depends media-gfx/imagemagick
[ Searching for packages depending on media-gfx/imagemagick... ]
gnome-extra/libgsf-1.14.2
gandalf ~ # equery depends gnome-extra/libgsf
[ Searching for packages depending on gnome-extra/libgsf... ]
gnome-base/librsvg-2.16.1
gandalf ~ # equery depends gnome-base/librsvg
[ Searching for packages depending on gnome-base/librsvg... ]
media-gfx/gimp-2.2.12
gnome-base/gdm-2.16.4
gnome-base/gnome-2.16.2
gnome-base/nautilus-2.16.3
gnome-extra/gnome-games-2.16.2
dev-python/gnome-python-desktop-2.16.0
gandalf ~ #

Note that this machine is about 350 miles away. Normally to emerge
things I run inside of a screen session and ^A^D out of screen while
it runs emerge. Because the machine is having troubles with Evolution
I re-emerged evolution and watched the compile. I'm seeing a number of
what appear to be link errors. Maybe that has something to do with
this?

What causes this problem:

libtool: link: warning:
`/usr/lib/gcc/i686-pc-linux-gnu/4.1.1/../../..//libxml2.la' seems to
be moved
libtool: link: warning:
`/usr/lib/gcc/i686-pc-linux-gnu/4.1.1/../../..//libgobject-2.0.la'
seems to be moved
libtool: link: warning:
`/usr/lib/gcc/i686-pc-linux-gnu/4.1.1/../../..//libbonobo-2.la' seems
to be moved
libtool: link: warning:
`/usr/lib/gcc/i686-pc-linux-gnu/4.1.1/../../..//libbonobo-activation.la'
seems to be moved

Thanks,
Mark
