+	# There are two circular dependencies to be aware of:
+	# 1)
+	# 	if we're bootstrapping configure and makefiles:
+	# 		libxcrypt -> automake -> perl -> libxcrypt
+	#
+	#   mitigation:
+	#		toolchain@ manually runs `make dist` after running autoconf + `./configure`
+	#		and the ebuild uses that.
+	#		(Don't include the pre-generated Perl artefacts.)
+	#
+	#	solution for future:
+	#		Upstream are working on producing `make dist` tarballs.
+	#		https://github.com/besser82/libxcrypt/issues/134#issuecomment-871833573
+	#
+	# 2)
+	#	configure *unconditionally* needs Perl at build time to generate
+	#	a list of enabled algorithms based on the set passed to `configure`:
+	#		libxcrypt -> perl -> libxcrypt
+	#
+	#	mitigation:
+	#		None at the moment.
+	#
+	#	solution for future:
+	#		Not possible right now. Upstream intend on depending on Perl for further
+	#		configuration options.
+	#		https://github.com/besser82/libxcrypt/issues/134#issuecomment-871833573
+	#
+	# Therefore, on changes (inc. bumps):
+	#	* You must check whether upstream have started providing tarballs with bootstrapped
+	#	  auto{conf,make};
+	#
+	#	* diff the build system changes!
