It completely depends on the environment variables. To benefit from
MacPorts, I have:

C_INCLUDE_PATH=/Users/vinc17/include:/opt/local/include
LIBRARY_PATH=/Users/vinc17/lib:/opt/local/lib

Anyway, since -L/usr/lib is used, it will have the precedence over
/opt/local/include and /usr/lib/libreadline.dylib will be used. And
indeed, no problem with it: if I unset LIBRARY_PATH, the build still
fails.

In short, I have:
/opt/local/include/readline/readline.h
/usr/include/readline/readline.h

BTW, I've noticed a bug: -L/usr/local/lib  -L/usr/lib is used at link
time, but only -I"/usr/include" is used at compile time, instead of
-I/usr/local/include -I/usr/include. Now, this doesn't explain the
problem I have.

If I unset C_INCLUDE_PATH, then the build doesn't fail. So, this means
that readline.h is taken from /opt/local/include/readline/readline.h
(with my C_INCLUDE_PATH), even though -I"/usr/include" is used. Any
explanation?
