Ok 128.238.56.59 (macosx104-i386) is setup with a buildbot user with your ssh key, and buildbot is setup as launchd service: http://buildbot.net/trac/wiki/UsingLaunchd

Aww, heavy reading!
How can i run the 'buildbot create-slave' command just once?

You can run it in the buildbot account using:

sudo /sw/bin/buildbot create-slave

The file is here, let me know if you need me to change it (probably):
/Library/LaunchDaemons/net.sourceforge.buildbot.plist

It seems only this...
<key>WorkingDirectory</key>
<string>/Users/buildbot/slave/test</string>
...needs to have the right path which shall be /Users/buildbot/macosx104-i386 once the slave is created.

If it cannot be run manually, we can try to fake it by copying (and modding) the files from another slave, shall we?

Ok, I edited it, and gave 'buildbot' rw perms, so you can edit if need be.  Let me know when you are done so I can convert it back to being owned by root.
