I don't know what happened to my initial message... Camlp5 http://pauillac.inria.fr/~ddr/camlp5/ SME Server compilation of a package I maintain (Geneweb) needs this to compile it's newest release. It has not been packaged for el4 which is what I am requesting. I would be willing to maintain the Camlp5 package. Thank you, Craig D. Jensen
