The fink folks are adding Module::Build support to their packaging system and noted... * Some naughty CPAN modules have Build.PL files that aren't Module::Build specific. For example, Adam Kennedy's Class::Autouse has a Build.PL that says 'require "Makefile.PL";' and the Makefile.PL is based on Module::Install. Why one would want such a Build.PL is beyond me. It breaks the Build.PL interface, Build.PL and Makefile.PL do not operate the same way and there will be no resulting Build program to run. Both users and automated installers will be confused. I would recommend simply deleting your Build.PL wrapper.
