Install failing on RHEL 7.6

[ludz-lim]

I'm getting the following error message when installing WWW::Mechanize on a RHEL7 machine using cpanm

t/frames.t ............................... ok

   Failed test '... and it was recorded in the history'
 at t/history.t line 131.
      got: '3'
   expected: '2'
 Looks like you failed 1 test of 28.

Do you have something running on localhost:80?

With this diff:

diff --git a/t/history.t b/t/history.t
index ee877be..b9b09ef 100644
--- a/t/history.t

+    diag np $mech->history;
 }

I see:

So, it looks like the test just assumes that there's no web server running and that a failure will end up in the history. We should change that POST to a local file GET or something similar. Just wondering if that's what happening in your case.

I have Apache running on that machine. I was able to install WWW:Mechanize after stopping apache.

FWIW, I'm currently being bitten by this same failing test. Current Debian, running Nginx on port 80.

Changing the t/history_2.html file so that the form target was http://localhost:6667 allowed the test to pass.
