Indeed.

I am a ~amd64 user and I just read the user-guide. :-)
I do not see any action items for my system; but do see a large number
of reinstalls proposed by emerge

I do not change any python variables in make.conf so emerge --info shows
PYTHON_SINGLE_TARGET="python2_7"
PYTHON_TARGETS="python2_7 python3_2"

a recursive grep -i for python in /etc/portage yields only
./package.use/imaging-pillow:5:virtual/python-imaging -python_targets_python3_2

So I basically have the default except for the imaging/pillow business.

I note that update world wants to rebuild a bunch of packages (the
entire output is below).  Some are qt-related others involve
PYTHON_TARGETS.

Does this mean that I can let the 44 packages / 38 reinstalls update occur
and expect a running system to result?  It is unusual, but I realize not
unprecedented, to have so many reinstalls and I would like to confirm
that this is expected.
