[CentOS] Upgrading mysql5 from centosplus

Hello List,

I have a regular install of centos 4.4 i386 (lately updated to 4.5), a
new application needs mysql > 5.0.x

The natural way to do this was:
yum --enablerepo=centosplus update mysql

However, after all the dependency / transaction checks.. i get this..

Now i did manage to solve the problem, which looked pretty 
straight-forward 'yum --enablerepo=centosplus update mysql php' (note: 
added php).. but shouldn't the dependency checker be taking care of this?
