The \clef command needs to be inside the music (inside the staff, to be 
precise). Also, you need to use "" for the clef name, else the number 
will be interpreted wrongly.
A few more hints:
– There was a space in \ break; also you need to add an invisible bar 
line { \bar "" } if you really want a line break, since Lily currently 
only allows breaking at bar lines.
– You should use proper lyric hyphens, which adapt to spacing.
– If you don’t want them to collapse in tight situations, you should 
override LyricHyphen.minimum-distance (commented below).
Here’s the full example:

%%%%%%%%%%%%%
\include "gregorian.ly"
\score {
  <<
    \new VaticanaVoice = "cantus" {
      \clef "vaticana-do2"
      \[ c'\melisma c' \flexa a\]
      \[ a \flexa \deminutum g\melismaEnd \]
      c' \divisioMinima \break
      \[ c' \melisma c' \flexa a \]
      \[ a \flexa \deminutum g\melismaEnd \] f \divisioMinima
    }
    \new Lyrics \lyricsto "cantus" {
      San -- ctus, San -- ctus,
    }
  >>
}
\layout {
  \context {
    \Lyrics
    %\override LyricHyphen.minimum-distance = 1
  }
}
%%%%%%%%%%%%%%

Yours, Simon

PS. Always include a \version statement with your code examples.
