  I was dealing with this myself today.  Here is the solution came
across which works for me.  I'm combining the stderr with stdout from
the system call.  You can remove the exitcode stuff if you dont need
it.

IO.popen("ls nofile 2>&1") {|f|
     output = f.read
     exitcode = Process.waitpid2(f.pid)[1] >> 8
     puts "this is the output"
     puts output
     puts "this is the exit code"
     puts exitcode
   }

#./test.rb
this is the output
nofile: No such file or directory
this is the exit code
