Upgrading LWP past version 6.46 fails with HTTP::Daemon 6.00 installed, works with 6.12.

[fitzmorrispr]

With HTTP::Daemon version 6, I would repeatedly get the following test failures when having cpan attempt an upgrade LWP or install OALDERS/libwww-perl-6.47.tar.gz,

#   Failed test 'request had cookie header'
#   at t/local/http.t line 426.
# GET /echo HTTP/1.1
# Connection: TE, close
# Authorization: Digest username="user2", realm="libwww-perl-digest", qop=auth, algorithm="MD5", uri="/echo", nonce="12345", nc=00000008, cnonce="603d7108", response="112cdaf9f6b079aef13c66f7219cb4e5"

#   Failed test 'request had only one cookie header'
#   at t/local/http.t line 430.
#          got: '0'
#     expected: '1'
# Looks like you failed 2 tests of 130.

this was despite t/00-report-prereqs.t reporting

# === Runtime Requires ===
#
#     Module                Want    Have
#     --------------------- ---- -------
#     [...]
#     HTTP::Cookies            6    6.00
#     HTTP::Daemon             6    6.00

I diffed the http.t files for version 6.46 and 6.47, and saw that the cookie tests, and their requirement for HTTP::Cookies were the only change, so I tried an upgrade HTTP::Cookies which installed 6.10, but had the same test failures.

Then, because I noticed that the file also used HTTP::Daemon, I did an upgrade HTTP::Daemon which installed version 6.12*. As soon as I did, upgrade LWP worked flawlessly. So it's pretty clear that 6.00 is not a high enough version, or at least, isn't on this system. It might be worth mentioning that the upgrade for HTTP::Daemon did skip some tests, saying Can't talk to ourself (misconfigured system) (something I don't have the privileges to fix)

*This also pulled in Module::Build::Tiny, which itself pulled in ExtUtils::Config, ::Helpers, and ::InstallPaths, but none of these were listed by report_prereqs.
(I already had ExtUtils::MakeMaker 7.10_02 and Module::Metadata 1.000031 which was all that report_prereqs seemed to want)

Thanks for reporting @fitzmorrispr!

Upgrading HTTP::Daemon from 6 to 6.12 is too strong. The reported t/local/http.t failure disappears when upgrading HTTP-Deamon from 6.00 to 6.01. HTTP-Daemon's changelog reads:

2012-02-18 HTTP-Daemon 6.01

If you bind localhost, don't trust gethostbyaddr() to resolve the
address.  [RT#67247]

I recommend lowering the minimal version to 6.01.

I will defer to @skaji on this.
