Conflict with I2C extension during installation

[mtanwr]

Hi, I am trying to install in Orange Pi Zero. I know there are other forks that updates the pin mapping, but I am ignoring that for now.

Installation aborts and shows the following:

I have python-smbus and i2c-dev tools installed. Could it be a conflict with those?

I went ahead with the installation by commenting out the I2C Extension section in setup.py.
