If you really need some package which does not exist in x86_64 version, use i386.

You don't actually require any i386 rpms at all if you're not using any i386 programs. You may find the output of the following two commands interesting: rpm -qa --qf "%{NAME}.%{ARCH}\n" | grep -v 'x86_64\|noarch\|gpg-pubkey' > list rpm --test -e $(cat list) You can remove all i386 packages with this command: yum remove \*.i?86 If yum tells you that it's removing something you need at this point, then you should obviously stop and fix it (with excludes or whatever) before continuing. -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com
