Failed 'make' with 2.17.27 from tarball

[Thomas Morley]

Hi,

for some testings I tried to compile 2.17.27 from the tarball to be found at:
http://lilypond.org/website/development.html
on Ubuntu 10.04 64-bit

Without success. The terminal-output points me to
contributor.makeinfo.log

This file contains:
"
/home/me/lilypondH/lilypond-2.17.27/Documentation/contributor/programming-work.itexi:69:
warning: @image file `lilypond/pictures/architecture-diagram.txt' (for
text) unreadable: No such file or directory.
out/contributor.texi:101: @verbatiminclude `ly-grammar.txt': No such
file or directory.
makeinfo: Removing output file `out/lilypond-contributor.info' due to
errors; use --force to preserve.
"

Do we have a problem?
