in reply to How does one redirect STDERR to a file? ((Filehandle, redirection, logging))

Redirect STDERR into a log file as the first thing your script does. Unfortunately, it's likely some module compile-time errors will go un-seen as a result, and get bumped into this stderr.log. Be sure to take a look there when you're debugging problems. 
BEGIN {
  open(STDERR, ">stderr.log");
}

    That probably wanted to be :- 
    BEGIN {
  open(STDERR, ">>stderr.log")
    or die "Failed to open log file";
}

    Note the >> and the or die.

    You could do this with a tied file handle too, as demonstrated recently by tilly - here
