+    make_ext.pl populates @INC correctly, don't override it badly
+    
+    PERL5LIB is populated by make_ext.pl with paths to the modules we need
+    to run, don't override this with "../../lib" since that may not have
+    been populated yet in a parallel build.

+    6695a346 changed the start of Makefile.PL, but t/posix.t reads that to
