systemd RPM dependency problem

We have run XenServer 6.2 and 6.5 successfully on this hardware. However having installed XenServer 7.0 I cannot install salt-minion.

I have tried installing systemd-python from the standard CentOS 7 version from
+ftp://rpmfind.net/linux/centos/7.2.1511/updates/x86_64/Packages/systemd-python-219-19.el7_2.7.x86_64.rpm
+but this complains

{{
[root@C5220-4-4 yum.repos.d]# rpm -i systemd-python-219-19.el7_2.7.x86_64.rpm
error: Failed dependencies:
systemd = 219-19.el7_2.7 is needed by systemd-python-219-19.el7_2.7.x86_64
}}

This is not a problem with salt-minion, instead its caused by systemd having a whacky package version, and then not having a suitable systemd-python RPM to match

I'm putting this as Minor because salt wouldn't be a common installation, but its a major block for me and the way we distribute system-wide changes.
