Building on Ubuntu 16.04, installing all the dependencies, and running make check install gave me this error:

The suggested fix I found that worked was to run (sudo apt-get install libxml2-utils xsltproc), though I already had libxml2-utils installed at the time so I was only missing xsltproc. Still, thought you might like to add it to the README.

So I'd say that this typically happens if you install asciidoc with --no-install-recommends the packages you want then are docbook-xsl xsltproc libxml2-utils I'm unsure of how common it is to not install the recommended packages and if we should add those to the list of dependencies.

[alistairewj]

Hm, maybe I installed it in an unusual manner? I did this exactly:

tar -xzf asciidoc-8.6.9.tar.gz
cd asciidoc-8.6.9/
./configure
sudo make install
sudo make docs

[klali]

Ah.. asciidoc built from source might not make this obvious.

In general, Yubico projects depend on their dependencies being installed via the appropriate package manager for each distribution -- it would be prohibitively time consuming to support this "expert" mode, and would further confuse the documentation (which, granted needs work) for the simple case.
