Now I have a question.  How do I tell Gentoo to make it pure 64 or a mix 
of 32 and 64?  I have read about this but I don't think I have actually 
seen where it is set.  Is it a profile selection, USE flag or something 
else?

If I decide on one then want to switch to the other, does that require a 
reinstall or just a change in settings and a recompile of world?

Since I use KDE, I always use Okular to view pdf files.  I assume KDE is 
64 bit ready.

Thanks.
