[STUMP] trouble requiring swank

[Eric Abrahamsen]

I'm on archlinux, trying to connect to my stumpwm process through emacs
using the instructions here:

https://wiki.archlinux.org/index.php/Stumpwm#With_Quicklisp_.28recommended.29

I'm using emacs 24 (from git), sbcl 1.0.56-1 (from the arch package),
swank installed via quickload, and slime from CVS.

When I try to eval (require 'swank) in stumpwm (preparatory to starting
the swank server), I get this error message:

--8<---------------cut here---------------start------------->8---

I really have no idea what would be causing this -- I've only got one
sbcl on my system, and it's definitely 1.0.56, so I don't know what
would be trying to use sbcl 1.0.54. I'm able to require sb-introspect
from a regular repl…

Any hints?

Thanks,
Eric
