[tex4ht] Can’t find/open file ‘xxx.dvi’ or ‘xxx.lg’

[Michal Hoftich]

It seems like a wrong make4ht installation. It cannot load any 
extensions. You may try instead this:

tex4ebook -c mycfg.cfg draft "svg" 

It should still produce SVG images for PDF files, but the compilation 
will be slower.

The generated Epub file is quite large, here is a link:
