[CentOS] yum upgrade not working

Hey all,

I'm attempting to upgrade a Centos 5.9 machine to CentOS 5.10.

But when I try the yum update command I get this response:

--> Finished Dependency Resolution
python26-PyYAML-3.08-5.el5.x86_64 from installed has depsolving problems
  --> Missing Dependency: libyaml-0.so.1()(64bit) is needed by package

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


The system claims that it can't find libyaml-0.so.1, however I can easily
locate it:

[root at ops:~] #locate libyaml-0.so.1
/usr/lib64/libyaml-0.so.1
/usr/lib64/libyaml-0.so.1.1.0

Can someone please point me in the right direction for solving these
problems?

Thanks
Tim
