           pkgsrc/lang/ruby193-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.
