It is...

I could have warned you :-) I tried that and spent a couple of days
trying to get it up and running (basing the compile on the hack I did
that managed to get it running in the first place). No way. I managed to
get it built but it would always segfault, no matter what I did. Finally
I decided to call it quits and use the hack - which apparently does not
work for everybody.

Wow! Good detective work!

It is working here, I have no idea why it does not in your case. I'll
pole around a bit more.

Don't look at me for advice :-)

At the time I looked at sbcl (a cmucl derivative) as an option. There
are rpms in the site and they built and did run fine. Regretfully at the
time clm did not have sbcl support. I think it does now, so I should
look at it again. I would really want to leave cmucl behind, the "can't
rebuild without a working cmucl" stumbling block is a major pain as was
proved by FC1.
