+# for some reason, make install installs some weird files in lib,

+# the original creator of perl.makemaker decided in 2003 that formal accomodation
+# of distros like Termux that can be described as "distros with timestamp-based packaging systems"
+# is undesirable because such a distro was either unheard of to them at the time, or
+# they imagined the hypothetical possibility of the present or future existence of such a distro
+# as an unsupportable edge case,
+# so the Makefile that perl.makemaker generates will not reliably install everything
+# unless all desired files are forcibly removed before make install is invoked
