yum update php/xmlrpc-c fails (RHEL6.1,PSA10.3.1)

[bluik]

I cannot update PHP nor xmlrpc-c on either of my RHEL 6.1 x64 boxes, both running latest Plesk with all MUs.
PHP update seems to clearly be some conflict because of Plesk (see the repository @PSA_10_2_0-thirdparty), xmlrpc-c I have no idea but I guess it is related to Plesk also.

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

Any ideas what might be wrong? I do not want to be stuck with an old version of PHP.
