Can't install GrovePi Software onto RPi2 running Raspbian

I followed the steps listed in this guide and hit error at Step 6. Encountered the error message “Something went wrong building/installing wiringPi, exiting.”.

Upon checking, this line of code is not working.
git clone git://git.drogon.net/wiringPi

I proceed to download and build the WiringPi manually and resume executing the rest of the install.sh. When I run i2cdetect, the GrovePi is not detected. Any help is much appreciated. Thanks!

Hey dpinc.coder, what point did the script break? What image or software are you starting with? What version of the Raspberry Pi are you running?

Is there any way you can try to use the Raspbian for Robots software? This should have the I2C and SPI setup and running.
