 It builds fine for me, but probably because I have more packages
 installed.

 See some upstream report:
 * https://gitlab.com/esr/cvs-fast-export/issues/7

 And many other similar issues all around the web:
 * https://github.com/mawww/kakoune/issues/939
 * https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=642717

 The upstream report says:
 > I think your main problem is that the DocBook DTDs aren't installed on
 your system.

 I suspect I saw this error earlier and most probably has to do with one
 DocBook DTD being installed and later removed. I forgot the details, but I
 believe an entry with previously installed files stays in some
 configuration file and then fails.

 While I could add more build dependencies to cvs-fast-export, it seems
 strange to have a defunct `a2x` on the server. Either asciidoc needs more
 dependencies or we need a more careful cleanup after a package gets
 removed.

 I can try to figure out more details later, but I wanted to open this
 ticket before I forget about it (and get bitten again at next update).
