FastLED.h and Pin.h can not be used in the same program

Hi, can annyone help me out with this:

When we have a sketch where we need to use fast in and outputs, then the libarary Pin.h is a faster way then digital.read and digital.write.

but when I want to use a Ledring (40 leds) I also need in this same sketch FastLED.

So the beginning of this sketch is:

#include <Pin.h>
#include <PinGroup.h>
#include <FastLED.h>

but when you try to compile this, you get the next error report:

In file included from C:\Users\Gebruiker\Documents\Arduino\libraries\FastLED/FastLED.h:48:0,

Fout bij het compileren voor board Arduino/Genuino Mega or Mega 2560

So they can not be combined together ??

Some libraries are incompatible with some other libraries, at least until you make some changes yourself.
