If the help2man perl script by lsb_release-1.4 is installed in /usr/bin
according the book instructions, the build fails with
[125/127] Generating pango-view.1 with a custom command.
FAILED: pango-view/pango-view.1
/usr/bin/help2man --no-info --section=1 '--help-option="--help-all"'
'--name="Pango text viewer"' --output=pango-view/pango-view.1
/tmp/pango-1.40.14/build/pango-view/pango-view
Unknown option: help-option
`help2man' generates a man page out of `--help' and `--version' output.
Usage: help2man [OPTION]... EXECUTABLE
-n, --name=STRING use `STRING' as the description for the NAME
paragraph
-s, --section=SECTION use `SECTION' as the section for the man page
-i, --include=FILE include material from `FILE'
-I, --opt-include=FILE include material from `FILE' if it exists
-o, --output=FILE send output to `FILE'
-N, --no-info suppress pointer to Texinfo manual
--alt_version_key=KEY use specified flag instead of --version
--help print this help, then exit
--version print version number, then exit
EXECUTABLE should accept `--help' and `--version' options.
The lsb_release-1.4 help2man does not accept the --help-option. With
sed '/--help-option=/d' -i pango-view/meson.build
it builds ok.
