can't upgrade bind

[Paolo Galtieri]

When I try to install the updates for bind on RedHat 6 I get the following
error:

Protected multilib versions: 32:bind-libs-9.7.3-2.el6_1.P3.2.i686 !=
32:bind-libs-9.7.3-2.el6_1.P3.3.x86_64 : Protected multilib versions:
32:bind-libs-9.7.3-2.el6_1.P3.2.i686 !=
32:bind-libs-9.7.3-2.el6_1.P3.3.x86_64

Is there a way to get around this error?  I can obviously un-install bind
and then re-install it, but this defeats the purpose of updates.
