I had a problem once, scared me to pieces until I got past it.  An
emerge had removed a library which was still used by the lvm command.
"ldd lvm" showed "not found".  Boot didn't like that.  I got lucky; a
rescue disk allowed me to create a bogus symlink to the old library so
that boot could proceed, at which point I remerged the broken command
and no longer needed the bogus symlink.

I have since written a perl program which looks for such broken libs.
I have no idea why gentoo's revdep-rebuild didn't find it.

I still use LVM and even gentoo, but I am also increasingly wary of
gentoo updates.
