Comment (by seamusdemora):

 Replying to [comment:6 ryandesign]:

 > The availability of precompiled archives is a nice-to-have, not a
 requirement. Prior to 2011, we did not offer any precompiled archives at
 all and we still got along fine. You can continue to install and upgrade
 ports at will. If no precompiled archive is available, it will build from
 source on your system. You can feel free to ignore these warnings, as
 those who have been updating the ports have evidently done so far as well.
 If a binary is available and you receive it, then you will not see the
 warnings since you won't have built the software, but that doesn't mean
 they didn't occur on the build machine where the software was built.

 2011 was "before my time"... I thank you for the history, but is it not
 also true that building just about anything on a Mac is more
 challenging/difficult than it was 15 years ago?

 IIRC, 2011 was the year I bought my first Mac - the 17" screen :)  As a
 user, I have noticed lately that things are often much more "convoluted"
 than they used to be - made far worse by Apple's appalling lack of good
 documentation. In the "overall" category, Mac wins - but that is primarily
 b/c the only competition is Microsoft.


 > There is no particularly good way for you to know in advance whether a
 binary is available or will be used. The only way that occurs to me is
 that you could check the directory listings on
 https://packages.macports.org to see if a file exists for the port name /
 version / variants / architecture / OS version you are about to install or
 upgrade.

 there's a reason why you need to know. If you want to install or upgrade a
 port, do so, and MacPorts will use the best method available.
 >
 > If you would like to only use precompiled archives, you can use the `-b`
 flag, as in `sudo port -b upgrade`. If no archive is available, MacPorts
 will error rather than fall back to building from source. However, some
 ports never have archives available due to licensing restrictions.

 I did check the listings on https://packages.macports.org. It ''seems to
 say'' that `ffmpeg7` has been successfully built for both my machines:
 macOS 26 (Tahoe), and macOS 10.14 (Mojave). However, on both of these
 machines, I had to also build it on my systems... have I missed
 something???

 And ''I never knew of the `-b` flag''. This is great information, Ryan;
 I'll certainly try that.

 I suppose it must seem that I'm one who never reads the documentation. But
 MacPorts has been so good - so effortlessly good - I never really had to
 dig in and find these things. That "era" seems to be over now. I just
 checked, and as of 5 minutes ago there are now **41,334 active ports** ...
 which strikes me as a huge number. Multiply that by the number of OS
 versions and architectures supported, and it is a huge number indeed. **My
 appreciation for the difficulty of your job has just increased!

 A question that comes to my mind at this point is one whose answer would
 probably increase your workload, but I'll ask it anyway: Is there some
 (automated) way to identify which ports (due to licensing restrictions)
 **never** have archives?

 I'll close with this: Kudos to all for resolving the "`libheif` issue"
 that crippled ffmpeg on my macOS Mojave system. I was finally able (just
 last night) to successfully build `ffmpeg7`. :))
