Here is a list of steps that should get you to a working Emacs+Clojure
SLIME on Mac OS X. I've also used it on Linux (without the MacPorts
command, instead using its package manager to install a working GNU
emacs).
If you don't have many MacPorts programs installed, or don't mind
reinstalling them, you can "nuke the site from orbit, just to be sure"
by removing /opt and everything in it, then do:
sudo port install em...@+x11
That will take a while. Then start up the X11 server, either the
default one that comes with OS X as an optional install, or Xquartz
from http://xquartz.macosforge.org
Hopefully /opt/local/bin will be earlier in your PATH than /usr/bin at
this point. Installing MacPorts should edit your shell's rc file to
do this for you already. You can check with "echo $PATH" or "which
emacs". The latter should show /opt/local/bin/emacs if everything is
set up to use MacPorts commands in preference over the default OS X
versions. If not, use the command:
PATH=/opt/local/bin:$PATH
preferably in your .bashrc or corresponding init file for the shell
you use. Then you can use the command "emacs" to start the MacPorts
version (which is GNU Emacs).
Follow the instructions on the ELPA page for installing it:
http://tromey.com/elpa/install.html
After you do M-x package-list-packages, go down the list of packages
until the cursor is on the line for the package "clojure-mode", press
the "i" key to mark it for later installation. Do the same for the
"slime-repl" package. Then press "x" to execute the installations of
those marked packages.
Install Leiningen by following the instructions on its home page.
Create a new project with it, like so:
lein new swank-clj-1.2
cd swank-clj-1.2
Now edit the file project.clj to look like this:
----------------------------------------
(defproject swank-clj-1.2.0 "1.0.0-SNAPSHOT"
:description "FIXME: write"
:dependencies [[org.clojure/clojure "1.2.0"]
[org.clojure/clojure-contrib "1.2.0"]]
:dev-dependencies [[swank-clojure "1.2.1"]])
----------------------------------------
Tweak the version numbers if you want to be closer to the bleeding
edge. Then run:
lein deps (this downloads JAR files if needed, and copies
them into subdirectory "lib")
lein swank
You should see this:
user=> Connection opened on local port 4005
#<ServerSocket ServerSocket[addr=localhost/
127.0.0.1,port=0,localport=4005]>
From inside of emacs, use the command:
M-x slime-connect
Press return after that, and you should see prompts asking you for the
IP address and port number. The defaults hopefully match the
127.0.0.1 and 4005 in the output of "lein swank", but if not, type in
values that do match the ones output from "lein swank".
If you see a message at the bottom of the emacs window like:
Versions differ: nil (slime) vs. 20100404 (swank). Continue? (y
or n)
Just press "y" and go on. I don't know exactly why that happens, but
it hasn't caused me any problems I've noticed.
An emacs buffer should be created with a Clojure prompt "user>". Type
the characters (, then +, then a space, and look at the bottom of the
emacs window and you should see the arguments taken by + as:
([] [x] [x y] [x y & more])
Or type "(pmap " (ending with a space character), and you should see
at the bottom its arguments:
([f coll] [f coll & colls])
You should also see similar hints when editing files in Clojure mode,
e.g. ones that end in .clj should automatically be in Clojure mode.

Sorry for asking here, but I think it's at least a little
relevant to
Clojure since I for one wouldn't be installing emacs if it
wasn't for
Clojure and Slime. Getting prompts about what the function
arguments
are seems like a HUGE benefit when learning this langauge. I
imagine
other non-emacs people might have a related question, so I'll give
asking this question a shot.
sudo ports install slime
Swank Clojure (the Clojure adapter for SLIME) depends on a
particular
version of Slime; the one in Macports is probably not it. I
recommend
installing via package.el instead as the swank-clojure readm
suggests:https://github.com/technomancy/swank-clojure#readme
Thanks Phil, I'll give that a shot.
Did that work?
If not, try installing a different emacs.
I don't use OSX, but with the installation process temacs and src
failing to load in the error message and all, I'd try that.

The short answer is that I've punted and have been using the
counterclockwise plugin for Eclipse. (http://code.google.com/p/
counterclockwise/) It is more excellent than I have any right to
expect. It does things like highlight the difference between macros
and functions, and that makes me happy.
I would still like to see slime in action, however. I have two emacs
installed, GNU and Aquamacs. macports is still not able to do anything
- I'm actually rather concerned about it's health.
$ emacs --version
GNU Emacs 22.1.1
I don't really know macports (or the native packager, pkgutil I think)
well enough to know what is responsible for installing that emacs.
