[tex4ht] tex4ebook error with latest texlive

[Chet Murthy]

I neglected to mention, but should have, that I removed all trace of
indexing from this sample, b/c it wasn't implicated in the most salient
"broken refs" errors that showed up.

I was not sure what you meant by this.  Perhaps you meant that the
build.lua and index.4ht needed to be present when tex4ebook is invoked?  If
not, could you explain how I should be using make4ht ?

Thanks,
