Yes, I have opened up tickets for these. An example of one is librsvg 
#68698 <https://trac.macports.org/ticket/68698>. For this example, it 
seems there are some proxy/SSL issues preventing that build (but other 
Cargo builds seem to work fine). I am not strong enough in proxy/SSL 
stuff and Cargo to take it any further than I have in that issue. In 
that example, I have access to a system that doesn't need to use the 
proxy (where librsvg builds just fine). Other times this is ameliorated 
when it is pre-built and the *.tbz2 file is downloaded from MacPorts, 
however many of the ports don't seem to have such a build for arm64 on 
Sequoia yet.

In general I agree. However, for weird corner cases such as my example 
above, it would be nice to be able to get a system operational (e.g., 
librsvg blocks quite a few ports) while the better fix is on the way.

That seems logical.

Overall, though, are my steps "correct" for what I want to do or is 
there a better way? Thank you for your help with this.
