Non-root users should use the above installation procedure, but must specify the
option to set a prefix a directory that is writable and also the -R option to prevent the package manager from attempting to update the package database.

pkg_add -p installation-directory -R lispworks-6.0.tgz
All directory names must be absolute pathnames. Relative pathnames and pathnames including shell-expanded characters such as
do not work.
