Those particular messages don't look related to your rpm installation
problems; look for avc messages with rpm_t or rpm_script_t in the
scontext or tcontext fields.
If you can narrow down what permission denials are relevant, you can
generate a local policy module that allows them as a temporary
workaround for your own use and file a bugzilla to get them added to the
base policy in a future update.
audit2allow can be used to generate policy from audit messages, but you
want to carefully review the result. See
http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385
and the audit2allow man page.
