This bug is certainly caused by symlinks in
Documentation/<LANGS>/user/out-www, which are left over from the old
build system.  There shouldn't be lily-* symlinks any more there.  I
don't know actually, because I made web-clean in
Documentation/<LANGS>/user/ (and only there) before testing the new
build system for the first time.

I can't reproduce this, so I guess you make web with EXTERNAL_BINARY,
which results in using an old lilypond-book, incompatible with the new
build system -- what actually happens is that old lilypond-book don't
find snippets in directories paased through -I command line option
(namely Documentation/user/out-www), so it rebuilds all ly snippets,
then mass-link.py tries to link lily-*.png's that already exist in
Documentation/user/out-www, which causes this failure.

Try the following trick: make a copy of latest master lilypond-book.py,
replace

"""
@relocate-preamble@
"""

with the preamble from your installation's lilypond-book, and overwrite
the latter with the new version you made by hand.

When building docs with EXTERNAL_BINARY, you're at the mercy of such
problems, but you know this :-), and fortunately the makefiles don't
change too frequently.

Anyway, I'll try to make mass-link.py more robust so it doesn't try to
link existing files.

Thanks for the report,
John
