+If some events detected in F<Makefile.PL> imply that there is no way

+This may be useful if other modules expect this module to be I<built>
+OK, as opposed to I<work> OK (say, this system-dependent module builds
+in a subdirectory of some other distribution, or is listed as a
+dependency in a CPAN::Bundle, but the functionality is supported by
+different means on the current architecture).
