wifi shiled Microchip MRF24WB0MA and DHCP

Hi, I have brought a wifi shield based on the Microchip MRF24WB0MA (http://www.electronics-lab.com/blog/?tag=mrf24wb0ma) and I have found this useful library to make it work (Google Code Archive - Long-term storage for Google Code Project Hosting.).
Do you know if there is another library that support DHCP like the one included in the IDE (WiFi - Arduino Reference) that unfortunatly works with another shield?

Thanks in advance for your help

Did you find a way to make DHCP work with this wifi chip?
I have the linksprite cuhead v2 wifi shield based on the same chipset and I cant get DHCP to work either...
