[racket-dev] dynamic require and collapsed snips?

The GUI-less error you were getting is a bug in the implementation of the
collapsed snip. Specifically it is not wired into the non-GUI reading
support stuff in the wxme library.

Unfortunately it does not seem easy to support the same strategy that the
GUI version uses
In the non-GUI context because the wxme library does not seem to provide a
way to say "here's a snipclass name; please read one of those from this here
port ".
