compiling -current

[Josh Lynch <tyme_(_at_)_visi_(_dot_)_com>]

simple question that's bugging me:
I keep getting this error at the end of compiling a new kernel (current
source):

conf.o: Undefined symbol `_iplread' referenced from data segment

it happens whether i compile on my i386 or sparc. the sparc is a snapshot
and the i386 is a 2.1. but just the kernel source is kept current (as of
3pm 9-23) whats happening here?

thanks
