  Modified files:
    Mk                   bsd.port.mk 
  Log:
  Add an anti-foot-shooting measure that protects against a dependent port
  being null, resulting in an entire category being depended on.  This was
  seen with missing USE_PERL5 definitions, for which there is now a test;
  however, it could theoretically be tripped over by other bad port
  Makefiles.  Since the failure mode is painful and seems unrelated to
  the lack of the definition (the build will fail at some random point
  within that entire category), IMHO it's worth the complexity tradeoff
  to put this in.
