|Perl: the Markov chain saw|
I don't know that it's correct or safe to jump to the conclusion that Tie::STDERR won't do what's needed, as the OP didn't specify in his original post that he was trying to catch errors that come from executing external commands.
Tie::STDERR will allow you to redirect any errors that come from Perl or Perl commands, but not from external (such as system() or `` backticks). It will even catch Perl's compiler errors, though as the POD states, the errors that it reports from the compiler aren't what you might expect to see.
So if you're trying to redirect the output from any Perl-generated errors, or errors that you generate internally in your script, Tie::STDOUT works great. But if you want to redirect external command errors, you'll have to dig deeper.
