[CentOS] yum hangs when installing uucp

Hello,
    I've got a CentOS 5 box. I want to install the uucp rpm to give access 
to the cu command. I do a yum -y install uucp and yum is hanging on the 
transaction test. I get the file downloaded fine, but on transaction test 
yum freezes and i have to kill it's pid to stop it. Any ideas?
    I'm looking for a program for serial terminals.
Thanks.
Dave.
