Make doc failure

[Carl Sorensen]

With current git, after make, make doc-clean, make doc I get

WARNING: Unable to find node 'Scheme tutorial' in book learning.
cp /Users/Carl/lilypond-working/Documentation/css/*.css out-www/contributor/
# fix links from other manuals to general
find ./out-www -name "*.html" | xargs sed -i 's/\.\.\/general\//\.\.\//'
sed: 1: "./out-www/All.html": invalid command code .
make[2]: *** [local-WWW-2] Error 1
make[1]: *** [WWW-2] Error 2

Thanks,
