Then it seems to me that the error message could say that possibly we
forgot to require *a* library.   (You surely know the speculations
about the cause of a problem issued by the TeX compiler.  I do not
remember I ever saw such speculations coming from Emacs.  Maybe the
byte compiler should first run a session with a doctor
(M-x emacs-psychotherapist) to narrow down the cause of the
problem...)
