 Since `-I/opt/local/include` is the very first include flag being passed
 to the compiler (i.e. highest precedence), I would guess
 `/opt/local/include/event.h` (from port `libevent`) is getting picked up
 instead. A similar case insensitive filesystem issue was encountered in
 ticket:63877#comment:6.
