You should do that because here we only want to fix pkgsrc-current and
for a few more weeks 2019Q4.  So if you want something fixed, or help,
we generally ask that you first update to something that isn't deprecated.

You need a compiler to start with.   How are you going to bootstrap
without a system compiler?

I would suggest that you start by having your base OS configuration
under configuration management.

If you are trying to build pkgsrc with a system compiler and then
rebuild things with native, and then move that around, it is tricky and
may be hard.

I think so, but this is not 100% solid as there are variables assigned
with = and with =?.

Part of the issue is that there is a notion of "user settable" variables
which should be in mk.conf (only) and "package settable" variables which
should be in packages (only).  But, sometimes they don't come in pairs,
and are abused.

It gets harder when people do unusual or nonstandard things.
