(CC'ed to boost and boost-build)

Two of Boost.Geometry users reported that peculiar error, [1] and [2]

in load
ERROR: rule "[[bbv2.builtin.features.warnings]]`warnings`::" unknown
in module "warnings-feature".

and I'm having a hard time understanding what is going wrong here
and what causes this issue, on Linux.

The line 27 is a typical Jam line:

feature.feature warnings
: on all extra pedantic off
: incidental propagated ;

but this refers to something that puzzles me most

ERROR: rule "[[bbv2.builtin.features.warnings]]`warnings`::" unknown

a bit of comment block?

#| tag::doc[]


Is this a parsing issue?
Is this related to potentially existing system-wide installation of Boost.Build?
If yes, why none of the dumps in [1] and [2] refer to any files in /usr?

[1] ./b2 headers attempt

[2] b2 attempt to build a program in libs/geometry
