The reason is a bug in the 14.0 Makefiles which are not exposing OSVERSION
(fixed in main, stable and will be in 14.1) and a behaviour fix in pkg 1.21.2
which highlights the main issue.

Up to pkg 1.21.2, pkg was leaking the OS version of the builder host into the
package, since pkg 1.21.2 pkg stops leaking that informaiton and so the version
if set to 0.

Waiting for 14.1 to be release the builders have to export OSVERSION variable.
the content of the variable should match what ever is the _FreeBSD_version in
the source being built, this information is available in sys/sys/params.h
