break the install by installing to /usr/usr/lib*)

+# I've reordered and extended the logic on when to invoke module-build versus
+# MakeMaker. The problem that has arisen is that some modules provide a
+# Makefile.PL that passes all arguments on to a Build.PL - including PREFIX,
+# which causes module-build to build with a target of /usr/usr/
+# (how broken is that?). Current logic is if there is a Build.PL and we aren't
+# overriding, use it; otherwise use the Makefile.PL; otherwise return (maybe we
+# want all the functionality of the perl-module eclass without needing to
+# compile??).
