About two times a year for the past two years, I revisit whether or not Makefile.pl or Build.pl is the standard way to "make" or "build" a perl module. In the past, I've read YAPC presentations detailing the fact that Makefile.pl is going away, read entries about how Build.pl was lacking the backwards compatibility of Makefile.pl, personally reviewed what usually shows up in the modules I'm downloading. At present, I am noticing more Build.pl scripts. Is it sample bias, or has the Perl community decided on a standard way to install (clearly this has nothing to do with Active State Installations, just Makefile.pl and Build.pl).
