Hi Fernando, it seems that there is a mistake in cmucl rpm, the permissions for lisp.h are badly set: $ ls -alrt /usr/lib/cmucl/lisp.h -rw------- 1 root root 1489 Jan 18 04:04 /usr/lib/cmucl/lisp.h It will be better to have 644 for an, header file ;) $ rpm -q -f /usr/lib/cmucl/lisp.h cmucl-2003.12-1.rh90.ccrma Bye. -- Patrice Tisserand <Patrice.Tisserand@ircam.fr>
