RF24 Library: Driver for nRF24L01(+) 2.4GHz Wireless Transceiver

Hi Guys.

I have two problems/questions
I have been playing with the nRF24L01 units for awhile now , and I have most of the examples working but I get a compile error when trying to verify the code . the code im trying tomake work is the sensornet pde. but i keep getting eeprom_update_block not declared. I have redone the file paths and and redownloaded the code but i get the same error over and over, and all the other examples work so that would tel me that the file path is fine.

im using 2x UNOs and IDE1.0.1
any ideas to fix this would be great.

the other problem i have is more on of advice needed. i want to use these units as maniacbug did for the sensor net but i want to send GPS data ,voltage and tempreture and date. which example would be best to start with and what would you suggest to use to send this data ?
