many problems could be there. Is your HW correct? How does your code look like. 
Are all pin/ports assigned correctly?

hmmm... i have not checked the c code for a whole. The port setting is not 
required, maybe you can comment out the u8g_SetPin command.

Everything else looks fine. Can you measure activity on the I2C pins?

Oliver
