Package: clisp Version: 2.38-8 In SBCL, I can say (require :cl-ppcre) and it works. In CLISP, however, it says "LOAD: A file with name CL-PPCRE does not exist". CL-PPCRE's webpage says it works under both SBCL and CLISP. Nothing I can find has led me to believe that there's any reason Debian's CLISP wouldn't work with Debian's CL-PPCRE. Other Lisp libraries I've tried, like (require :aserve), also work in SBCL but not CLISP. (Portable Aserve, upstream, also claims to work with CLISP.) Maybe I'm missing something crucial about how to load libraries in CLISP, but this seems like the common case that one can expect to work. I saw nothing in the CLISP or CL-PPCRE docs that look relevant, either in the upstream docs or the Debian package docs. Thanks! - Ken
