There have been some efforts like this (etc.) for Emacs on CL:

I have never been able to get one to work, though.

MIT Scheme also has an Emacs 18 compatible editor called edwin written in Scheme.

Hemlock was written as part of CMUCL and is still supplied with it. The portable version is also used as the editor in Clozure CL.

What didn't work for you ?

I tried Portable Hemlock from Quicklisp, and IIRC it would not install from the repos.

On Clozure, the IDE with Hemlock only runs on OS X--I use Linux.

The one in CMUCL might work, but I haven't tried it because they only have 32 bit support for x86.

I wasn't trying to be dismissive--I would really like to run Emacs on CL!

CMUCL will run on 64-bit Linux, that is how it is built. There would obviously be a smaller limit to file sizes than if Hemlock were running in a 64-bit Lisp.
