I am currently facing a strange problem when tryping to upgrade
following ports:

# pkg version -vIL=           
py38-pycparser-2.20                <   needs updating (index has 2.21)
py38-pyparsing-3.0.4               <   needs updating (index has 3.0.6)
py38-snowballstemmer-2.1.0         <   needs updating (index has 2.2.0)

All mentioned ports cannot be upgraded from ports source tree. For e.g.
py38-pycparser I get:

===>>> Starting build for devel/py-pycparser@py38 <<<===

This command has been saved to ~/portmasterfail.txt

The error is the same for the remaining two other ports.

And even if I tryp to reinstall py38-setuptools I get the same error.

I am out of ideas and during my attempts to narrow down the error I
reinstalled python38 - which at least works without problems.

My Python and PIP versions are:
# pkg version |grep -iE "pip|python38"
py38-pip-20.3.4                    =
python38-3.8.12_1                  =
