HelloWorld.pde compiles fine, maybe check within the Arduino Environment

With 1.04 and my LC7981 Display I can't get this to work - even the 
HelloWorld.pde fails on me.
I think my problem is that the pin names inside the constructor are confusing. 
Why is /CS needed and equals RS=DI?

I got my display working with just D0..D7, RS, E, RW.

Please, can anyone help?

RS and DI are different names for the same pin. 
RS = Register Select
DI = DATA/Instruciton
The LC7981 has a chip select input line. This pin must have input low to accept 
data or instructions. U8glib can control this "CS" input or you can pull this 
line to GND.
If CS is not used, put U8G_PIN_NONE at this position in the constructor.
U8GLIB_LC7981_160X80 u8g(8, 9, 10, 11, 4, 5, 6, 7,  18, U8G_PIN_NONE, 15, 17, 
16);
