It's encouraged to use GPG version 2.1 (See release notes here https://www.gnupg.org/faq/whats-new-in-2.1.html ).
If you are using OSX with brew, then you could use this:
brew install homebrew/versions/gnupg21
- Put the PGP/GPG exported keys received by email into the keys/ directory
- Run make
- Open the printout.html in a browser

Explicitly avoided using a HTML2PDF converter to reduce the number of requirements.
