I do not know why that error occurred.
What's the problem?
Below is the error message.




Code: 
Arduino:1.6.7 (Mac OS X), TD: 1.28, Board:"Teensy 3.2 / 3.1, Serial, 96 MHz optimized (overclock), US English"

Hi and welcome,

As mentioned at the top of the forum, please include the sources, to reproduce.

I am assuming from the error messages, that you are using the ShiftPWM_RGB_Example program that is in the examples for the library.
I tried loading it, found that it would not compile without: #define SHIFTPWM_NOSPI
So I uncommented that line, plus the two lines below and it appeared to compile
 
Code: 
/************************************************************************************************************************************
 * ShiftPWM blocking RGB fades example, (c) Elco Jacobs, updated August 2012.
 *
 * ShiftPWM blocking RGB fades example. This example uses simple delay loops to create fades.
 * If you want to change the fading mode based on inputs (sensors, buttons, serial), use the non-blocking example as a starting point.
 * Please go to www.elcojacobs.com/shiftpwm for documentation, fuction reference and schematics.
 * If you want to use ShiftPWM with LED strips or high power LED's, visit the shop for boards.

Thank you for answer.
I used to compile and uncomment the two parts.
#define SHIFTPWM_NOSPI
const int ShiftPWM_dataPin = 11;
const int ShiftPWM_clockPin = 13;
 
Change this line

Code: 
#include </Users/Jymno/Downloads/Arduino 3.app/Contents/Java/hardware/teensy/avr/libraries/ShiftPWM/ShiftPWM.h>   // include ShiftPWM.h after setting the pins!

to this:

Code: 
#include <ShiftPWM.h>   // include ShiftPWM.h after setting the pins!

I verified it compiles correctly. Here's screenshot:
