Hah ... your backpan link led me to realize the actual problem with
Test::More. It got folded into Test::Simple at some point, and
evidently cpanm isn't smart enough to handle a request for a back
version in such cases. But this works:
$ cpanm install Test::Simple@0.87_01
...
$ perl -MTest::More -e 'print $Test::More::VERSION, "\n";'
0.8701
So we oughta recommend that instead. Now I'm wondering what
version of IPC::Run to recommend.
