..., when I went to start slime, I ran into some problems.
Specifically, the command buffer in emacs states: itimer "run-with-timer" signaled: (error "127.0.0.1/(^W1^H& Servname not supported for ai_socktype")
I'm running XEmacs 21.4.17, and my clisp --version reports Software: GNU C 4.0.2. I'm running on the "breezy" version of Kubuntu Linux (Ubuntu).
I'm seeing the same problem with the same XEmacs, also on Kubuntu (5.10). It seems that open-network-stream won't work with a number as a port argument.
As a work-around you can add the following function to your slime.el and replace the 2 calls to open-network-stream with my-open-network-stream: (defun my-open-network-stream (name buffer host port) (open-network-stream name buffer host (if (numberp port) (number-to-string port) port) 'tcp))
When you google around a bit it seems that there was indeed a problem with open-network-stream in that XEmacs version.
