Issues with fonts ant RA8875 display driver

[maxdog]

I'm stumped.
Fresh install of Arduino IDE (latest version)
Installed the teensy board/libraries per the instruction on the PRJC web site.
Grabbed one of the font examples (ILI_Ada_FontTest2), copied and pasted it in to a new sketch. For the sake of troubleshooting and this post, I trimmed it down to be very basic.
It wouldn't compile initially, with an "error: conflicting declaration 'typedef struct ILI9341_t3_font_t ILI9341_t3_font_t'".

Here is the code:

#include <Adafruit_GFX.h>
#include <SPI.h>
#include <RA8875.h>
#include "font_Arial.h"

#define RA8875_CS 10
#define RA8875_RST 14

RA8875 tft = RA8875(RA8875_CS, RA8875_RST);

void setup() {
  tft.begin(Adafruit_800x480);

  tft.fillWindow(RA8875_BLACK);
  tft.setTextColor(RA8875_WHITE);
  tft.setFont(Arial_14);

  tft.print("I'm Frustraed");
}

void loop()
{

}

The full error I am getting is:

I've been banging my head on this for too long. I read several forum posts, which is why I uninstalled all boards, library, and the IDE and started fresh. Anybody have any ideas?

Thank you.
