Messiah version for the sake of updating

[Francisco Vila]

Hello. This is mainly for Monsieur N. Sceaux. I have been trying to
compile nenuvar/Haendel/Oratorio/Messiah and the standard way via
'make' does not work for me with lilypond 2.19.9.

First of all, I'd like to update the code to a more recent version,
but my question is, what version is Messiah's code at? I can say
Haendel/Opera/GiulioCesare is in \version "2.11.57" for example, but
did not find any version statement in Messiah.

If you were going to compile all of nenuvar/ , where would you start from?

Thanks!
