Implement Python Externally Managed Environments (PEP 668)

[Kimmo Suominen <kim%netbsd.org@localhost>]

Hi all,

I'd like to see Python in pkgsrc implement the Externally Managed
Environments spec to have pip and other Python installers guide users
towards virtual environments by default, instead of installing in the
paths that are expected to be managed by pkgsrc.

https://packaging.python.org/en/latest/specifications/externally-managed-environments/

Any suggestions on the best way to implement that?

Kind regards,
+ Kimmo
