[tex-live] Errors messages installing/updating TL2013

Hi guys,

many emails, with a lot of mixture up...

Ok, that is a bug in our code, in paticular in TLDownload::get_file,
there we have
  my $response = $self->{'ua'}->get($url, ':content_file' => $realout);
  if ($response->is_success) {
    ... do something
  } else {
    tlwarn("TLDownload::get_file: response error: "
            . $response->status_line . " (for $url)\n");
  ...

So *this* error message is not a problem, it simply is that our
	tlwarn
references something that is not set. Probably I mis-read the specification
on LWP, but nothing to worry about.

THese things can happen, network errors, and after that wget kicked in,
all fine:

Agreed here , I will try to fix it ...

This is a *VERY* different error:

This means that the installation of LWP is messed up, something
that on MacTeX we cannot influence.

We = tlmgr = TLDownload::get_file makes a call to 
	my $ua = LWP::UserAgent->new
followed by
	$self->{'ua'}->get...
which break in LWP ... we do *not* call 
	can_read
directly.

So this indicates an error of LWP installation on your system.

But fortunately, wget is used to retry with success:

> TLUtils::download_file: retry with wget succeeded:

(good that I implemented this fallback mechansim ..)

No, they are not, they only look similar because the part up
to the 500 is the same, but the reason is coming after this.

==========================================================

Bottom line:
* we have to fix the code, but thisis not urgent, since it is only
  a warning message rom our side
* LWP on MacTeX on GWIII's computer seems broken, nothing we can do.
