So the solution is simply to put the _definition_ of not-last-page inside the 
\paper block!  Indeed, this works as expected:

\paper {
  #(define (not-last-page layout props arg)
    (if (not (book-last-page? layout props))
        (interpret-markup layout props arg)
        empty-stencil))
  oddHeaderMarkup = \markup { \fill-line {
    \null
    \fromproperty #'page:page-number-string
    \concat {
      \on-the-fly #not-last-page { "More ..." }
      \on-the-fly #last-page { "No more." }
    }
  }}
  evenHeaderMarkup =  \oddHeaderMarkup
} 
\markup{}
\pageBreak
\markup{}

Thanks,
