Just force the install and forget about it. ...or read on, and then force the install.

Look at the real error report:

089: t\die-in-setup.t ...............
090: t\die-in-setup.t ............... 1/1 #   Failed test 'die in setu
+p caused test method to fail'

In other words, the test failed because the output was:

Failed test 'setup_method (for test method 'test') died (oops - we die
+d)'
at t\die-in-setup.t line 27.
(in Foo->setup_method)
[download]

...when the expected output was...

Failed test 'setup_method (for test method 'test') died (oops - we die
+d)'

at t/die-in-setup.t line 27.

(in Foo->setup_method)
[download]

The test failed over the placement of three newlines -- possibly a line-endings cross-platform incompatibility. It's an innocuous failure at worst (and really rather silly).

So by all means, force the install using sisyphus's suggestion above.
