Connecting LCD via l2c interface on pins other than A5 and A6

slevinx:
I thought that l2c pins are logical, not physical and they can exist on any analog pin. My bad i guess.

No, if you wish to use the internal AVR hardware I2C then you are stuck with the pins they are hardwired to inside the chip.

However there are most likely 'software I2C' libraries out there somewhere that would allow you to select the pins you wish to use. Do a little searching or maybe wait for someone with first hand knowledge about such libraries.
