This is actually an old issue that has already been fixed in #17 and I can see you are still using v0.1.6. Please use v0.1.7, the version has already been bumped in nixpkgs so I'm not sure why you are still using the old one: https://github.com/NixOS/nixpkgs/blob/master/pkgs/tools/text/mdbook-pdf/default.nix

If you have any difficulties with that, check
#14 (comment)
