New version dependency (Bison 2.0) in Lilypond 2.5.8 ?

[Matthias Neeracher]

It seems that 2.5.8 now needs bison 2.0, due to its use of %locations 
(not sure when that was introduced, but it does not work in 1.28). The 
documentation says bison 1.25 or higher is required, so that probably 
should be changed.

Also, the dependency on freetype should be on version 2.1.4 or higher, 
I believe (2.1.3 misses some symbols that lilypond needs).
