I doubt there is a dependency on elyxer. elyxer is just a lyx2html converter written
indepedently and stalled now for a few years.
I guess that you've to reconfigure LyX so it knows that elyxer is no longer available.
That's something you can only do in the GUI so far.
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=397464
and
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=816173
is also partially related.

So if you do not use LyX for interactive document writing just rm -r ~/.lyx in your
build environment and it should reconfigure on the next invocation.

Another possibility would be that lyx fails to import and convert the manual to the
current LyX 2.2.x document format.
Which repo are you building from right now? I'd like to try it out just to see what
happens.

Cheers,
Sven
