There are two different versions of portaudio.
Portaudio V18 includes a function Pa_StreamActive().
The equivalent function in Portaudio V19 is Pa_IsStreamActive().

Therefore, eSpeak must be compiled to use the correct version of
portaudio which you have installed on your computer.
(The pre-compiled eSpeak is compiled to use portaudio V18).

Your error message says that function Pa_StreamActive() is not found. 
This means:

1.  You are compiling eSpeak to use portaudio V18.

2.  Portaudio V18 is not installed.

You say that you've installed portaudio V19.  So you need to compile
eSpeak to use Pa_IsStreamActive() instead of Pa_StreamActive().

To do this, copy the file (in eSpeak's src directory)  portaudio19.h 
and rename it to portaudio.h  to replace the original portaudio.h
(which is a copy of  portaudi18.h).  Then compile eSpeak.
