Ok. Newer CPAN knows what to do with Build.PL. So assuming it prefers
Build.PL over Makefile.PL (which is generally accepted correct behavior now),
all we have to do is die "Run Build.PL or use CPAN v1.9102 or higher" in the
Makefile.PL and let the user figure out the rest. If it _doesn't_ prefer
Build.PL it should should be changed so it does prefer it unless the user
is intentionally being extremely silly.

Makefile.PL is supposed to be dying. Let's just kill the beast. Let
the first step to automating installation be installing new automation
tools. perl -MCPAN -e 'install Bundle::CPAN'. Is there any reason this isn't
a reasonable requirement?

M::B updates when (current) Bundle::CPAN does. So.. just do it?
