After a few tests I'd like to confirm:

• seems that any py-termplotlib subport is failed;
• I can install on the same machine under the same version of python into fresh venv;
• I can install it also on non M1 machine.

Seems that it is regression in pyparsing: ​https://github.com/pyparsing/pyparsing/issues/329 which was updated yesterday: ​https://github.com/macports/macports-ports/commit/a83905f74d75383236de152c43264983fce58e02
