Please create a small example.  In this case,

\version "2.7.0"
{ c'4}

produces:

spark:~/tmp gperciva$ lilypond foo.ly
GNU LilyPond 2.9.8
Processing `foo.ly'
Parsing...
error: Incorrect lilypond version: 2.7.0 (2.7.38, 2.9.8)
error: Consider updating the input with the convert-ly script
foo.ly: 0: warning: no \version statement found, please add

\version "2.9.8"

for future compatibility

Knowing that there are two error messages printed is worthwhile.
