[CentOS] yum killed, ipa\* and xorg\* a mess

yum update was killed at an inopportune time, leaving ipa\* and xorg\*
in an inconsistent state.  

yum-complete-transaction looks like it it's going to erase the entire 
system and then fails.

>From the transaction files, the following are in:

install 0:ipa-python-2.2.0-17.el6_3.1.x86_64
install 0:ipa-client-2.2.0-17.el6_3.1.x86_64
install 0:xorg-x11-server-common-1.10.6-1.0.1.el6.centos.x86_64
install 0:ipa-admintools-2.2.0-17.el6_3.1.x86_64

rpm -q ipa-server returns:

ipa-server-2.2.0-16.el6.x86_64
ipa-server-2.2.0-17.el6_3.1.x86_64

rpm -q ipa-server-selinux returns:

ipa-server-selinux-2.2.0-16.el6.x86_64

Thinking I could remove the old and then drop in the new, I tried:

rpm -e ipa-server-2.2.0-16.el6.x86_64 ipa-server-selinux-2.2.0-16.el6.x86_64

but that fails with:

ipa-server-selinux = 2.2.0-17.el6_3.1 is needed by (installed) ipa-server-2.2.0-17.el6_3.1.x86_64

Normally I'd not be hesitant about trying different options, perhaps
with --nodeps, and then reinstalling if my inexperience proved to be
fatal, but this machine is not unimportant, so any advice is greatly
appreciated.

Thanks very much for your time.

Cheers,
