pkg install -f ... doesn't?

After recent upgrade to 13.4,
daily security says py39-pycparser checksum doesn't match.
Attempting to reinstall doesn't reinstall.
What am I missing?

# pkg check -s py39-pycparser
Checking py39-pycparser:   0%
py39-pycparser-2.21: checksum mismatch for /usr/local/lib/python3.9/site-packages/pycparser/__pycache__/c_ast.cpython-39.pyc
Checking py39-pycparser: 100%

# pkg install -f py39-pycparser
