Test::SDK breaks Test::Harness Makefile

The problem is simple:

With older Test::Harness in system, when you type "install
Test::Harness" on CPAN shell now, it will install Test::Harness
into site_perl directory, instead of "perl" directory, you know. 

This will cause core-bundled Test::Harness and CPAN distributed
Test::Harness co-existence glitches.

The analysis follows:

Though Test::Harness is distributed standalone, CPAN shell
recognizes it's part of Test::SDK modules, so fetches it, unpack
it, runs Makefile.PL. 

I guess this breaks Test::Harness's Makefile.PL option
'INSTALLDIRS=perl', because Test-SDK Makefile.PL doesn't have it. 
(I dunno much about MakeMaker, so this is only a guess)
