py37-pip fails to build

[andrewfree]

When trying to install py37-pip it fails to build. I have attempted to run port/clean and uninstall old version but still having issues. I included the build log below

It seems to come down to this.

:info:build PermissionError: [Errno 13] Permission denied: '/opt/local/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/x509-0.1-py3.7.egg/EGG-INFO/entry_points.txt' :info:build Command failed: cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_python_py-pip/py37-pip/work/pip-20.2.4" && /opt/local/Library/Frameworks/Python.framework/Versions/3.7/bin/python3.7 setup.py --no-user-cfg build -j12
