Alright, it took only 1 line to make it work on both 1.8.5 and previous
versions:

$ ruby183 -v method_args-pre185.rb benchmark
ruby 1.8.3 (2005-09-21) [i686-linux]
Benchmark#benchmark (caption = "", label_width = nil, fmtstr = nil, *labels)
Benchmark#bm (label_width = 0, *labels)
Benchmark#bmbm (width = 0)
Benchmark#measure (label = "")
[...]

I've updated the code on eigenclass.org; could you give it a try?
(btw. no need to apply the patch in the comments, I had already done so)
