It entered 2005-12-19, short before 1.80_57. But note, that the
protection I was talking about is not the fact that M:B is in the
Bundle:CPAN. The protecion looks instead like so:
if (-f "Build.PL" && ! -f "Makefile.PL" && ! exists
$req->{"Module::Build"}) {
$CPAN::Frontend->mywarn(" Warning: CPAN.pm discovered Module::Build as
".
"undeclared prerequisite.\n".
" Adding it now as a prerequisite.\n"
);
This code ensure that M:B gets installed right at the moment where it
is actually required.
