HTTP::Daemon has undeclared dependencies

[jkeenan]

Today I attempted to install Test::Smoke against Perl 5 blead using cpan as the installer. The cpan utility detected two undeclared dependencies in HTTP::Daemon.

Module-Build and Module-Build-Tiny were reported as unsatisfied. Can you investigate?

So did you fail to install HTTP::Daemon?

No, `cpan` is smart enough to add the two undeclared dependencies and install them. I'm merely calling the lack of declaration to your attention.

HTTP::Daemon requires Module::Build::Tiny,
and cpan.pm correctly detected it and tries to install it.
I don't see anything wrong.

Module::Build is not related to HTTP::Daemon, directly.

This is an issue of cpan.pm, I guess,

@jkeenan do you have an old CPAN.pm? see the big block of text in Build.PL that calls to your attention an old toolchain.
