[...] the second transformer procedure only works if eq? is in

Unfortunately, the result of `make-rename-transformer' isn't a
procedure (Matthew, could this be changed?), so you can't use it
here.
The (planet cce/scheme) package includes `redirect-transformer' for
this purpose. Just use (redirect-transformer #'eq?) and it will
produce a transformer procedure that does the right work.
Thanks, Sam and Carl!
I've rewritten the forms using redirect-transformer and released the
fixed code as Unlib 3.20.
