make buildworld fails

[Maarten de Vries]

Hi,

I'm trying to upgrade an old P166 from 5.0 to 5.1-R using freshly cvsup'ed 
sources. After a couple of hours (heh...) it suddenly halts:

/usr/obj/usr/src/i386/usr/lib/libtermlib_p.a -> libncurses_p.a
/usr/obj/usr/src/i386/usr/lib/libmytinfo_p.a -> libncurses_p.a
/usr/obj/usr/src/i386/usr/lib/libtinfo_p.a -> libncurses_p.a
1 error
*** Error code 2
1 error
*** Error code 2
1 error
*** Error code 2
1 error

Bummer. Anything I can do to fix this?
