I found the solution on this page: http://mathertel.blogspot.com/2013/04/using-spi-bus-with-ethernet-sd-card-and.html
The key is setting the Chip Select (CS) line to be different for each module.
For the CC3000...
"#define ADAFRUIT_CC3000_CS 7"
Pin 7 is being used exclusively to select the Wifi module.

For the NRF24L01+...
"RF24 radio(9,10);"
Pin 9 is being used for Chip Enable (CE) and Pin 10 is Chip Select (CS).

The other SPI pins: CLK, MISO, MOSI, are shared by the two modules and get wired in parallel.
Hi do you still have a Gateway code when using CC3000 and arduino Mega or UNO(if it fits)?
