If one needs a TAP::Harness aware EU::MM (or an M::B that makes
TAP::Harness the default), then they need configure_requires.

Of course there is.  When CPAN.pm is configured not to install
build_requires dependencies, the appropriate blib entries of those
modules are added to PERL5LIB, which will take precedence over
installed modules.
