==================================
You need a working asciidoc installed to be able to build the manpage.

a2x is installed, but for some reason it isn't working.  Sometimes
This happens because required docbook support files are missing.
Please install docbook-xsl, docbook-xml, and libxml2-utils (Debian) or
similar.

Alternatively, to build without manpages, use the --disable-asciidoc
argument when calling configure.
