yum Error Messages Linux Newbie questions

New to Linux. I've been a homebuilder and computer hobbyist forever. My first computer was a Kaypro 4 running CP-M (still have it, photos available on request ;-) ), but I've been running FC 5 64bit for only about a month and am just learning about Linux software installation. I tried to install Yumex, which is just a graphical shell for yum, but the install failed with a bunch of error messages -- yum's output for the task is reproduced below. As near as I can tell, the installation failed because Yumex tried to install some policies that conflicted with existing SELinux policies (not sure about this -- see the output below and correct me if I'm wrong). I considered changing the permissions in SELinux, but after trying to read up on it I was more confused than when I started. Obviously, having a Yumex installed on this computer is not a necessity and it wouldn't be much of a loss if I just forgot the whole thing and went on to other tasks, but it seems wise to learn what I can from this so I don't repeat any mistakes in the future. The yum output is reproduced below. All comments welcome.
