Changes to how outputters work it would seem.  Adding a custom stencil
command requires different work:

%%%%
% #(module-define! (resolve-module '(scm output-ps))
%   'dashed-path dashed-path-ps)

#(let* ((module (resolve-module '(scm output-ps)))
         (alist (module-ref module 'stencil-dispatch-alist '())))
   (module-define! module 'stencil-dispatch-alist
    (acons 'dashed-path dashed-path-ps alist)))
%%%%

As shown above, replace the logic that defines dashed-path as a
procedure within the output-ps module instead with logic that appends a
new dispatch entry.

With that, I was able to use 2.22.0 and compile my original code
otherwise unchanged.
