Compile error benh-2.6

[Nirmal Govind <nirmalg@asu.edu>]

Hi,
 
While I'm still hoping for a solution to the network/router problem I'm having, I decided to compile the 2.6 benh kernel. I downloaded the source using rsync from mvista yesterday. The compile fails with the error below.. not sure what the problem is..  Please let me know if there's a fix to this.
 
Thanks,
nirmal
