Well, what happens is that in some archs (specifically PowerPC in our
case) it's very common to have a biarch environment (i.e., 64-bit kernel
and mixed 32/64-bit userspace), so it's not a strange thing to have both
versions of some software installed in the system. I've used Perl as an
example, but I can cite a lot more packages that may need to be
installed correctly in a biarch environment (Python, PHP, Ruby, Apache).
That's the rationale behind my question :-).

BTW, can you please tell me where can I find the multilib definition?
I've been reading
http://fedoraproject.org/wiki/PackagingDrafts/MultilibTricks , but I
don't know if it's official.

Thanks,
