This happens with almost every large library-based module. I'm not sure if you are asking about Makefile.PL as in ExtUtils::MakeMaker or Module::Install based distributions. I don't use either of those directly. I do use EUMM-based Makefile.PL's via Dist::Zilla for some modules, but not any of the ones complicated enough to require dealing with Config.pm. I did this for Math::Random::ISAAC::XS: http://cpansearch.perl.org/src/JAWNSY/Math-Random-ISAAC-XS-1.004/Build.PL It was just to determine the correct compiler flags to use. Without more details I'm afraid I can't be more helpful. Cheers, Jonathan
