This page http://www.gentoo.org/doc/en/gentoo-amd64-faq.xml says: "Warning: Currently you cannot switch from a no-multilib to a multilib-enabled profile, so think over your decision twice before you use the no-multilib profile." Now, I know that I can install most of the emul-linux-x86-* stuff and that will probably be enough for me, but I was wondering what the technical problems iwould be if I just changed my /etc/make.profile to point to a multilib profile. As far as I can tell, gcc and glibc would be rebuilt with USE=multilib, and a new set of libraries would be installed into /lib32 and /usr/lib32 (in addition to those already installed under the corresponding lib64 locations). So, how would that break the existing applications? Thanks for any insight.
