[CentOS] RPM dependency graphical viewer

Greetings,

Has anybody come across a graphical dependency viewer for the RPM / YUM based package managers?

The reason is I am unable to update to Centos 5.3 due the fact that mine is an experimental system and I have had to use various repos in the past. now it is somewhat impractical for fresh install. I do not have a whole lot of H/W.

I don't mind pruning the dependency manually if I get a view -- even if it is a pstree/tree like output.

Also I am yet to make headways with OO3

and oh, my uname -a shows Linux custom.xxxxxxx.com 2.6.18-92.1.22.el5 #1 SMP Tue Dec 16 12:03:43 EST 2008 i686 i686 i386 GNU/Linux

TIA

Regards,

Rajagopal
