Hello Monks,

I'm setting up continuous integration for some Perl modules and I have an issue with configure phase dependencies. My CI script looks like this:

#!/bin/bash -ex

workspace=$(mktemp -d)

function cleanup {
    rm -Rf "$workspace"
}

trap cleanup EXIT

perlbrew exec --with ${perlaxis} "cpanm -nvL '$workspace' --installdeps . && prove -I'$workspace/lib/perl5/' -lrvm t/"

For instance, one module requires Module::Build version 0.4004 or later (for test_requires support). So Build.PL has

configure_requires => {
    'Module::Build' => '0.4004',
},

This works when installing the packaged distribution because I can generate META.json, and so cpanm is aware of the configure phase dependencies. However, during CI, we are typically installing dependencies and running tests based on a clone of the repository, which doesn't contain META files (since those are supposed to be generated). So cpanm doesn't know about configure phase dependencies (and since it doesn't upgrade M::B, it also misses the test dependencies, and everything explodes).

What's the right fix here? (In my CI script or in Build.PL or anywhere else.)
