[CentOS] wireshark install did not seem to work

I needed wireshark on a test system; I had not installed it at setup time.

So I did a yum install wireshark

This seemed to have worked, but there is no executable that I can 
locate, and wireshark in not in the gnome panel.

So I looked at a system were I had installed wireshark intitally, and I 
see a symlink for it in /usr/bin to consolehelper. 

What do I do to get wireshark working?
