sometimes the conflicting module blows up, and Dist::CheckConflicts doesn't even say why!

e.g.  http://www.cpantesters.org/cpan/report/30139470-921d-11e3-8ff6-0265e0bfc7aa
Dist-Zilla-Plugin-Test-CheckBreaks-0.004

          - keep usage of ::Conflicts module inside an eval to protect against
            blowing up when a conflicting module fails to compile
