I would too... But, I just spent 3 weeks hacking like a fiend
to rescue the CL version of CLM ("clm-3") and I hope to have it
ready by sometime next week.  I had stopped work on the previous
version (clm-2) because the code made me angry just looking at
it, so it was either a total rewrite, or abandon CL.
