Yes, probably because the Makefile is incorrect.

No:

prunille:~> locate include/readline/readline.h
/Developer/SDKs/MacOSX10.4u.sdk/usr/include/readline/readline.h
/opt/local/include/readline/readline.h
/opt/local/var/db/dports/build/_Users_vinc17_software_darwinports_dports_devel_readline/work/destroot/opt/local/include/readline/readline.h
/opt/local/var/db/dports/software/readline/5.1.004_0/opt/local/include/readline/readline.h
/opt/local/var/db/dports/software/readline/5.2.001_0/opt/local/include/readline/readline.h
/usr/include/readline/readline.h

The problem is a mismatch between Apple's linker and gcc. A
-I/usr/include is ignored by gcc (because it is in the system path),
while with -L/usr/lib, this directory has the precedence. In short,
using -L/usr/lib is incorrect.
