emerge complains that icu (details below) will overwrite files that MAY
belong to other packages. But in fact none do. The suggestion is to
ignore the collisions. Does that mean I should simply rm the files
before retrying the emerge?

thanks,

Yes. If you think these files might be important, then you could back them
up first. Apparently they belong to the icu stuff you are going to remerge
anyway, so deleting should be safe I think. But it's strange that those
files do not belong to any package.

Instead of removing them it would be easier to set FEATURES to -collision-
protect. And with FEATURES=keepwork you will not have to recompile icu. So,
I would do this:

FEATURES="-collision-protect keepwork" emerge -1a dev-libs/icu

Remember that you have to delete stuff in /var/tmp/portage/dev-
libs/icu-4.6.1 manually afterwards.

thank you for the advice, which worked fine.

I could swear I saw the same/similar message about collisions, but in my case
the package emerged and the files were overwritten. Not sure if I have some
FEATURES setting that took care of this.

You probably do not have FEATURES="collision-protect" in make.conf, it
is not activated by default.
The similar FEATURE protect-owned is set by default, but this only
refuses to overwrite files belonging to another package.
