Can't find ports openssl11 and openssl3

[dlegaultbbry (David Legault)]

I'm using the git installation method on Catalina 10.15.7 and half the ports I want to install can't because of these missing dependencies. I can see them in the github repository.

I'm also seeing a bunch of these when I sync ports to latest.
