no library called "libcairo-2" was found

I updated PIP3 first and then installed without issue. Running omnigraffle-stencil --help provide the following output:

I see this library makes a ton of problems after quick google search. Can you tell what exactly commands did you run to install dependencies and on what system you are?

I'm currently running MacOS Mojave 10.14.6 (e.g., current version). I'm pushing back reinstalling from scratch with Big Sur for couple of months. If we can't fixed this easily, I'll bite the bullet and start that operation. This is MacBook Pro (15-inch, 2018) 2.9 GHz Intel Core i9 with 32GB ram.

I upgraded PIP3 from 21.1.3 to 21.2.2 first with /usr/local/opt/python@3.9/bin/python3.9 -m pip install --upgrade pip.

Then I installed omnigraffle-stencil with pip3 install omnigraffle-stencil. It looked like I installed the package before ... I got this output:

I tried to update CairoSVG with pip install CairoSVG with the following result:
pip install CairoSVG
