I've tried to integrate MakeMaker 6.12 into perl-5.6.2, and it turns out that it isn't a good idea.
Basically that's because in perl 5.6.1 MakeMaker intergrates
-I$(PERL_LIB) : see for example
MM_Unix.pm:3495:MKPATH = $(PERL) -I$(PERL_ARCHLIB) -I$(PERL_LIB) -MExtUtils::Command
-e mkpath
But in bleadperl :
MM_Unix.pm:1963: $self->{MKPATH} ||= '$(PERLRUN) "-MExtUtils::Command" -e
mkpath';
So I'm deciding to not upgrading MakeMaker, at least not for 5.6.2.
