[CentOS] remove RPMs with cyclic dependancies.

But will this work when the original isntall was done with RPMs and not YUM?
I attempted to install OpenOffice.org Beta via YUM, but couldn't find it 
in a repository. So I had to isntall it from the RPMs offered on the 
OpenOffice.org site. Then, when I tried to uninstall it, I tried:
# yum remove openoffice*
... and:
# yum remove openoffice
... but it didn't work.
If I have something installed without YUM, how do I use YUM to uninstall it?
