There are two problems here.

1.  The "portaudio" library is not installed on your computer.  eSpeak
uses this for sound output.

You can still compile the stand-alone "speak" program (instead of
"espeak" + "libespeak").  Remove this line from the makefile:
AUDIO = portaudio

Without portaudio, "speak" can still produce WAV files, eg:
  speak -v en -w output.wav  "Hello world"

but it can't play sound directly on the computer.

2.  The system library function sem_timedwait() is not available.  It
should be defined in the header file:
#include <semaphore.h>

but perhaps it is not available on Mac?
This problem will not affect the compilation of the stand-alone "speak"
program.
