Which, indirectly, leads to a question I had.  I know this has been asked 
before, but I can't find the reference.  Perhaps this is a FAQ?

In any case, what is the Ruby way for getting the stderr from an executed 
command?  The only way I've been able to do this is via shell piping:

        `foo 2>&1`

I've tried backquotes, %x{...}, and popen, and I've tried redirecting 
stdout to stderr via $stdout.reopen(...).  In no case can I get the stderr 
from the process.

Thanks,
