[CentOS] bugzilla on C5?

I'd like to test/play with bugzilla on my CentOS 5 system.  I tried yum 
install bug* but that came up empty.  I tried a google for yum install 
bugzilla and found a few people who had apparently done it...

I then went to the bugzilla web site and downloaded 3.0.2, extracted it to 
a directory of my choice, then visited the Quickstart file.   Initial 
trial of perl -MCPAN -e 'install GD::Graph' yields some errors I'm not 
versed in deciphering on how to fix.

Help is most appreciated.

Thanks.

Scott
