Well, I fear that perldoc.bat isn't the culprit at all.  Since this
little batch file doesn't change the environment, it doesn't matter
whether it's found in tlperl or any other Perl distribution.

It seems that removing the file is not enough.  Let's assume that this
problem occurs on Windows only. Then 

  if ($opt_help) {
    if (TeXLive::TLUtils::which("perldoc")) {
      pod2usage(-exitstatus => 0, -verbose => 2);
    } else {
      pod2usage(-exitstatus => 0, -verbose => 2, -noperldoc => 1);
    }
  }

should probably better be replaced by something like:

  if ($opt_help) {
    if (win32) {
      pod2usage(-exitstatus => 0, -verbose => 2, -noperldoc => 1);
    } else {
      if (TeXLive::TLUtils::which("perldoc")) {
        pod2usage(-exitstatus => 0, -verbose => 2);
      } else {
        pod2usage(-exitstatus => 0, -verbose => 2, -noperldoc => 1);
      }
    }
  }
    
Not a nice solution but I think that Windows users are hardened enough
in order to deal with this inconvenience.

It seems that there is a severe bug in Perl, though.

Regards,
  Reinhard
