And of course, the way you solve this is to have both the i386 and
x86_64 versions installed.

This is a huge con, as it becomes much harder to maintain updates.  You
need to modify you rpmmacros to see both the i386 and x86_64 packages.

If you are going to try to compile anything on a multi-lib arch machine,
you will need to create separate chroots (or VMs with xen / vmware.
etc.) so that you can compile programs that work on either another
x86_64 or i386 machine ... as 64 bit and 32bit stuff will be compiled
otherwise.

You will also have problems getting some i386 software installed over
the x86_64 software as there are shared doc files and shared man files
the sometimes conflict with each other.

Personally ... unless I know for a fact that I will not need any i386
software, I install i386 and not x86_64 distro.  If I wanted a
workstation, I would not install x86_64.  That is just my opinion.
