When trying to install dhcp via yum I get TypeError: 'NoneType' object is unsubscript

Hi guys.
I just tried to install dhcp server package on my Fedora 8, using yum.
After I type the usual command (yum install dhcp), during the dependency resolving (it needs openldap-servers package as well to function) the yum application fails and it spits out a lot of data:

Could this be a temporary issue at repositories end or something?
I get the same result on my physical or even any of my virtual fedora 8 machines that I have. It is the openldap-servers package that's causing this (I've tried to download it seperately through yum). Any ideas? Thanks in advance!
