upgrading fromo current of 11/05 to today

Having issues upgrading (buildworld part) from my CURRENT of November of 
2005, yes that's old, sorry, to "today" --- here's the end of the 
buildworld so far:

  -I/usr/src/lib/libc/rpc -DYP -DNS_CACHING -Wsystem-headers -Werror -Wall 
-Wno-for
mat-y2k -Wno-uninitialized -c /usr/src/lib/libc/net/res_init.c
/usr/src/lib/libc/net/res_init.c:120: error: field `res_state_ext' has

*** Error code 1

Stop in /usr/src/lib/libc.
*** Error code 1


... Sin ce this is in libc, I assume I am missing something *basic* 
(unless shit hit the fan).

thank you for any help,
andrew
