  Modified Files:
          pkgsrc/lang/ruby22-base: Makefile distinfo
  Added Files:
          pkgsrc/lang/ruby22-base/patches: patch-lib_mkmf.rb

  Log Message:
  Avoid to generate empty command line on some platforms:

  $(DLLIB): $(OBJS) Makefile
  ...
          $(Q) $(POSTLINK)

  And POSTLINK is empty macro.  In such case, GNU make ignore empty command
  line but BSD make tries to execute it and causes error.

  Bump PKGREVISION.
