I believe I'm responsible that the wording is there in this form. The
reason for this is that most users start emacs via some application
launchers -- and thus do not get the environment variables from
.bashrc/.tcshrc/profile.
Furthermore, the working directory from which emacs is started is most
of the time not where the Dylan projects are.

Thus, it is in my opinion less confusing to ask users to provide an
absolute path to their Dylan projects within .emacs.

The problem solved by registries is locating libraries. A registry can
provide platform-dependent library files (.lid). Meaning if you have
several independent large projects, and a registry for each of them,
you do not need to specify in any of the projects where the others are
located on your disk.

I'm happy to help here. Which FreeBSD version and platform are you on?
i386? amd64?
