+The latest version of the package will be chosen on linux but the middle
+version will be chosen on macos as that's the only version available on macos.

+  Solution for dune.macos.lock:
+  - macos-sometimes.0.0.2
+
+A warning will be printed as the undefined-var.0.0.1 package has an undefined
+variable in its `available` filter. The undefined-var.0.0.2 package has a valid
+`available` filter but is only available on linux.

+The middle version will be picked as this is the only one available if
+with-test is set. This exercises that we can handle flags in the available
+filter.
