libpsl @0.21.0-20200315 : Build fails on Mac OS X 10.5.8 due to python38 dependency

[SerpentChris (Chris Calderon)]

libpsl requires python38 as a build dependency, but there are unresolved issues with python38 on Mac OS X 10.5.8 (see #59772). Would it be possible to revert this back to python37 or perhaps add python37 as a variant? libpsl is a dependency of curl, and through curl git, neither of which can be built on Leopard right now because of this python38 requirement.

There is an upstream PR <​https://github.com/python/cpython/pull/19008> for python 38 that has not yet been reviewed.

Hope for a soon as possible fix to continue

I'm trying to build it right now with python37 instead of python38. What I've done is a simple edit to the libpsl Portfile found at /opt/local/var/macports/sources/rsync.macports.org/macports/release/tarballs/ports/net/libpsl/Portfile. I've replaced the strings "python38" and "python3.8" with "python37" and "python3.7", respectively. I will comment here again when it finishes building.

Well it finished building without any errors. I'm building curl and git now. I'll try ffmpeg afterward.
