Are you looking at the same interfaces(5) we are?  Mine says:
   The dhcp Method
       This method may be used to obtain an address via DHCP with any of the tools: dhclient,
       pump (Linux 2.2.x and newer), udhcpc (Linux 2.2.x and newer), or dhcpcd. If you have a
       complicated DHCP setup you should note that some of these clients use their  own  con­
       figuration files, rather than obtaining their configuration via ifup.

I've used all of them successfully today.
