I can see at mkmf.rb in Ruby 1.8.0 source

  depend = File.join(srcdir, "depend")
  if File.exist?(depend)
    open(depend, "r") do |dfile|
      mfile.printf "###\n"
      while line = dfile.gets()
 line.gsub!(/\.o\b/, ".#{$OBJEXT}")
 line.gsub!(/(\s)([^\s\/]+\.[ch])/, '\1{$(srcdir)}\2') if $nmake
 line.gsub!(/\$\(hdrdir\)\/config.h/, $config_h) if $config_h
 mfile.print line
      end
    end
  end

I tried extconf.rb after renaming depends to depend.
All works fine.
