You’ll want to let pkg-config find those values for you. On my system, I get:


$ pkg-config ruby-2.1 --cflags
-I/opt/local/include/ruby-2.1.0/universal-darwin13 -I/opt/local/include/ruby-2.1.0 
$ pkg-config ruby-2.1 --libs
-L/opt/local/lib -Wl,-undefined,dynamic_lookup -Wl,-multiply_defined,suppress -lruby.2.1.0 -lpthread -ldl -lobjc 
$
