Great little distro and super for my headless controller application.

I am trying to install a real time clock - , but after installing i2c-tools I am getting the following:  
when i2cdetect used:

> could not open /dev/i2c-0

I had the same issue with Raspian Wheezy and had to use raspi-config to enable i2c kernel hardware  
There must be a file to configure , but I cannot find it, can anyone advise please?
