ccache @3.7.6_0: build fails in xsltproc, needs docbook-xsl-nons

[schallee (Ed Schaller)]

Without docbook-xsl-nons installed the build of ccache fails converting MANUAL.xml with xsltproc because the xschema's needed are not available.

As the build command used, a2x from asciidoc @8.6.9_3, generates the error from an internal call to xsltproc this may be a dependency issue in the asciidoc package that only manifested itself for me in ccache.

After installing docbook-xsl-nons @1.79.2_0 the build successfuly generates ccache.1 and the install succeeds.

Thanks for all the work on macports!

Clemens, what do you think? Should a runtime dependency on docbook-xsl-nons be added to asciidoc, since it is the asciidoc file /opt/local/etc/asciidoc/docbook-xsl/manpage.xsl (and some of its other files as well) that references the docbook xsl files?

This was also suggested in #53943.

In 9875cffcfdb567e35e6a8d38608d46c73e6d3f91/macports-ports (master):

asciidoc: Update to asciidoc-py3 9.0.0rc1

Switch to a version that supports python 3.x, use python 3.7, set
license_noconflict openssl because asciidoc doesn't use openssl, it just
uses python, which links against openssl.

Since this is a source distribution now, we need to run autoreconf.
Additionally, the libxml2, libxslt, docbook-xml-4.5 and docbook-xsl-nons
dependencies are now also required at build time. Add them as library
dependencies to ensure asciidoc works when compiling manpages, because
that might require files from docbook-xsl-nons.
