problem compiling RELENG_6

[Michael Eubanks]

I've CVSup'd my RELENG_6 source and tried a make buildworld.  Compilation
breaks with the following error:

===> sbin/ipf/libipf (depend)
make: don't know how to make extras.c. Stop
*** Error code 2

I noticed there was another post with this same problem at
http://unix.derkeiler.com/Mailing-Lists/FreeBSD/hackers/2007-11/msg00203.htm
l, although, I'm curious if there is a fix?


Thank you,
 Michael Eubanks
