How to install liberation fonts with macports on macOS for Inkscape?

I'm new to macOS and I've tried to install liberation fonts with macports:

sudo port install liberation-fonts

But it looks like this doesn't install the fonts on the system. When I open Inkcape I don't see the fonts. I used this command to find where they are located:

port contents liberation-fonts
Port liberation-fonts @2.1.5_1 contains:
  /opt/local/share/fonts/TTF/LiberationMono-Bold.ttf
  /opt/local/share/fonts/TTF/LiberationMono-BoldItalic.ttf
  /opt/local/share/fonts/TTF/LiberationMono-Italic.ttf
  /opt/local/share/fonts/TTF/LiberationMono-Regular.ttf
  /opt/local/share/fonts/TTF/LiberationSans-Bold.ttf
  /opt/local/share/fonts/TTF/LiberationSans-BoldItalic.ttf
  /opt/local/share/fonts/TTF/LiberationSans-Italic.ttf
  /opt/local/share/fonts/TTF/LiberationSans-Regular.ttf
  /opt/local/share/fonts/TTF/LiberationSerif-Bold.ttf
  /opt/local/share/fonts/TTF/LiberationSerif-BoldItalic.ttf
  /opt/local/share/fonts/TTF/LiberationSerif-Italic.ttf
  /opt/local/share/fonts/TTF/LiberationSerif-Regular.ttf

Do I need to click on every font and install it manually or is there a way to automatically install the fonts? Or maybe do I need to reboot to install the fonts? I can't find any information how to install the fonts, Google AI suggestion only says that installing macport is enough. Then why the fonts are not installed? Do I need to refresh the font cache like on Linux? Or maybe there is a different reason why installed fonts don't appear in Inkscape?
