#23 problem creating a zip containing a binary

[Chas12345]

I'm trying to create a zip file that contains a dir with binary files inside of it.

used this as a point of departure...
with src is a dir containig 2 binaries (.mp3 files)

<--zip_binary.rb---->

require 'rubygems'
require 'zip/zipfilesystem'
require 'FileUtils'

stuff = FileUtils.cp_r 'src/.', 'order' #this copies the files fine...

Zip::ZipFile.open('my.zip', Zip::ZipFile::CREATE) do |zip|
zip.file.open('my.zip', 'w') { |f1| f1 << stuff }
end

<----end zip_binary.rb---->

This results in an empty zip file "stuff.zip" which contains a dir named "order 2".

I've also tried "wb' unsuccessfully and "a" and "a+" with the errors below (respectively)

generally i get these errors
/usr/local/lib/ruby/gems/1.8/gems/rubyzip-0.9.1/lib/zip/zipfilesystem.rb:234:in open': openmode 'wb not supported (StandardError) from t.rb:9 from /usr/local/lib/ruby/gems/1.8/gems/rubyzip-0.9.1/lib/zip/zip.rb:1382:inopen'
