Sorry! I jumped to conclusions about the problem.

The following works for me on linux. Can't make any predictions about
OSX, tho'.

require 'open-uri'

open("http://path.berkeley.edu/~vjoel/redshift/ruby-sdforum.pdf"){|u|
   targetFile = File.new("test.pdf","w")
   u.each_byte {|ch|
     targetFile.putc ch
   }
}


Why are you doing it a byte at a time? This seems to run much faster for me:

require 'open-uri'

open("http://path.berkeley.edu/~vjoel/redshift/ruby-sdforum.pdf") do |u|
  targetFile = File.new("test.pdf","w")
  loop do
    dat = u.read(1000)
    break unless dat
    targetFile.write dat
  end
end
