  Libs: -lreadline
  Cflags: -I/usr/include/readline
+
+==== macOS Homebrew
+
+Ensure that {{pkg-config}} and {{readline}} have been installed via
+Homebrew.
+
+Consider Homebrew's remarks after installing readline:
+
+ readline is keg-only, which means it was not symlinked into /usr/local,
+ because macOS provides BSD libedit.
+ 
+ For compilers to find readline you may need to set:
+   export LDFLAGS="-L/usr/local/opt/readline/lib"
+   export CPPFLAGS="-I/usr/local/opt/readline/include"
+ 
+ For pkg-config to find readline you may need to set:
+   export PKG_CONFIG_PATH="/usr/local/opt/readline/lib/pkgconfig"
+
+Therefore export all of these, then run {{chicken-install breadline}}.
+
+In case it still doesn't work and {{pkg-config --libs readline}}
+fails, this may be the fault of an incorrect {{readline.pc}} file,
+see [[https://github.com/Homebrew/homebrew-core/issues/38972|Homebrew's issue tracker]]
+and update.
