Thanks for your reply.

What I've done on two of my gentoo systems is, what had been suggested in
one of the earlier replies to this thread. I ran emerge -C `grep -i libs
/var/lib/portage/world`, followed by emerge @preserved-rebuild.
While on another one of my systems I tried emerge --deselect `grep -i libs
/var/lib/portage/world`, followed by emerge --depclean.

As a result, I no longer have any libs in my world set.

I should probably put sys-libs/gpm back into the world set via emerge
--noreplace, based on what you said about the package.

I should probably look into what does and what doesn't have to go into the
world file. Up until recently I assumed that portage would figure that out
for me.
