I've packaged SLIME and swank for Fedora at:
http://yum.octopodial-chrome.com/packages/cl-swank http://yum.octopodial-chrome.com/packages/emacs-slime http://yum.octopodial-chrome.com/packages/emacs-slime-el http://yum.octopodial-chrome.com/packages/xemacs-slime http://yum.octopodial-chrome.com/packages/xemacs-slime-el
Probably the easiest thing to do is to install the octopodial-chrome package and then run 'yum install cl-swank emacs-slime.'
They're packaged separately in order a) to follow Fedora guidelines b) provide more flexibility in deployment.
