Problem in making lilypond

[Giancarlo Niccolai]

Hello;

I am trying to compile my first try with lily, but when the make system 
reaches the info making point I have got a long sequence of errors:

make[2]: Leaving directory `/home/gian/Progetti/lilypond/stepmake/stepmake'
make[1]: Leaving directory `/home/gian/Progetti/lilypond/stepmake'
make[1]: Entering directory `/home/gian/Progetti/lilypond/Documentation'

./out/macros.texi:115: warning: macro `internalsref' previously defined.
./out/macros.texi:93: warning: here is the previous definition of

And then, the make system goes loop saying "Too many errors!  Gave up." 
forever. Any idea? How can I proceed?

Giancarlo.
