weird buildworld consequences in 6.0

[David Coder]

i've an up-to-date 5.4 system that i'd like to upgrade to 6.0 to take
advantage of the improved SMP but keep running into the following, using 
pristine 6.0 sources & (as far as i can see) following the UPDATING advice
scrupulously, namely that after running make buildworld & make kernel, using
the 5.4 ldd gives me either:

# ldd /usr/obj/usr/src_6/bin/sh/sh
/usr/obj/usr/src_6/bin/sh/sh:
         libedit.so.5 => /lib/libedit.so.5 (0x2809c000)
         libncurses.so.6 => /lib/libncurses.so.6 (0x280b2000)
         libc.so.6 => /usr/local/lib/pluginwrapper/flash6.so (0x280f5000)

when i try to boot into single-user to install world; and the 6.0 ldd gives me

# pwd
/usr/obj/usr/src_6/usr.bin/ldd
# ./ldd ../../bin/sh/sh
/libexec/ld-elf.so.1: Undefined symbol "__stdoutp" referenced from COPY relocation in ./ldd

which i sometimes also get, & that doesn't work very well, either.

anybody got a clue what i'm doing wrong?

thx.
