Thanks for your brilliantly helpful response.
Yes.. the pings are indirectly to blame!!
No, I am not running a third party firewall.
But I read the notes and noticed the comments about
changing the max_hosts_to_ping: I had noticed
after the hang that there were upwards of a dozen
hung pings.
In order I had done the following
1. After 24 hours I tried the exact same port upgrade command again...
same result.
2. So, ok, after 15 minutes or so, I donned my debugging hat and executed:
port -v -v -v upgrade outdated
... now it did not choke on gd2! ... several other packages are
installed .... then it hangs on ghostscript!!
Clearly, something extremely odd was going on here. I think it has
nothing to
do with turning on debug (-v -v -v) -- I think that is a red herring.
It seems that some other condition on the network cleared,
possibly a condition on the macports mirror, which now allowed gd2
to download. Yes consistent with the ping stuff... variations in response
to pings could easily give different result
So I change the max_hosts_to_ping to 10.
Eureka. It works. No hang.
It is very clear, I believe, that there is some serious bug
in MacOS networking stack which is present not only in BigSur
but also in Catalina.

Running MacOS 10.15.7 on MacBook Pro 2016
I am updating various already installed packges in the usual way:
sudo port upgrade outdated
Everything goes along fine until the software reached gd2.
I then see:
---> Fetching archive for gd2
---> Attempting to fetch gd2-2.3.3_1+x11.darwin_19.x86_64.tbz2 from
https://packages.macports.org/gd2
---> Attempting to fetch gd2-2.3.3_1+x11.darwin_19.x86_64.tbz2 from

---> Attempting to fetch gd2-2.3.3_1+x11.darwin_19.x86_64.tbz2 from
https://ema.uk.packages.macports.org/gd2
---> Fetching distfiles for gd2
At this point the networking on the machine hangs.
I cannot kill the port process. I cannot reach the
offending machine even by ping; I cannot use
the network from another terminal nor browser.
Are you running any third-party firewall? This looks a lot like
<https://trac.macports.org/ticket/61683>, though that was on Big Sur. I
would agree it's certainly an OS bug in any case.
You can try the edits mentioned in the ticket to see if it's the pings
that are triggering the bug. A quick workaround if you just need to get
gd2 installed is to download the distfile manually as per
<https://trac.macports.org/wiki/ProblemHotlist#fetch-failures>.
