Yodl 4 required?

[Bart Schaefer <schaefer@xxxxxxxxxxxxxxxx>]

I've got yodl installed from (I believe) macports on my laptop, and
it's yodl version 3.05.01.
On my Ubuntu host I have yodl version 4.02.02.

With version 4.02.02, all is well.  With 3.05.01, I get these errors
trying to build zsh.texi:

./zsh.texi:18929: Prev field of node `Character Highlighting' not pointed to.
./zsh.texi:16894: This node (Zle Widgets) has the bad Next.
./zsh.texi:17432: Next field of node `Standard Widgets' not pointed to
(perhaps incorrect sectioning?).
./zsh.texi:18929: This node (Character Highlighting) has the bad Prev.
./zsh.texi:6361: Node `Filename Expansion' lacks menu item for `Notes'
