hmmm, I have 7 emul-linux86 packages, but portage did not offer to
replace them when I checked today for a world update -- I didn't want to
remove them manually, I thought it might do more harm than good.  I am
not sure whether I need any 32-bit libraries, although I do have
multilib enabled, but I wonder about those emul-linux-x86 packages.  Any
way for me to tell what is going on here such as dependencies on 32-bit
libraries?
