In October, the date reported by gpsd will jump back by 1024 weeks:

https://gitlab.com/gpsd/gpsd/-/issues/144

This will be fixed in the upcoming 3.23 release:

https://gitlab.com/gpsd/gpsd/-/issues/144#note_636906629

This is a serious problem because gpsd is commonly used as a time source
for network time servers.

I tried updating our package from 3.21 to 3.22, to help prepare for this
important update, but the build fails during the configure portion of
the SCons 'build' phase as shown below. I'm not familiar with SCons so
I'm not sure which is the salient error.
