The source tarball link [ http://common-lisp.net/project/cl-syslog/cl-syslog_latest.tar.gz ] in syslog webpage is not the latest. In fact it is 3 years older than the latest. It does not contain the migration from UFFI to CFFI. The author propably has not updated the link. I founded it because using it in SBCL 1.1 throws an error whenever user tries to use the main log function. The latest CVS source though works fine.
Where is the CVS?
