I did though (which is the confusing part). What I did when trying to 
upgrade from 6.0 to 6.1-PR2:

make buildworld; reboot; # booted into single user mode.
make installworld; # failed here partway through claiming that 
dependencies hadn't been compiled.
make buildworld; # still failed
#many makes later and make all's later
make installworld # success
exit
#login attempt
/libexec/ld-elf.so.1: Shared object "libintl.so.6" not found, required by 
"-bash"
#rebooted into single user mode.
#sed'ed /etc/passwd and /etc/master.passwd to change shell from /bin/csh
exit
#repeat from login attempt.

I've chased down the library to gcc, and I did later clean and remake 
libiconv, gettext, and bash, but still no dice (get the same error 
message as before).

Did that just a while ago; thanks for the tip. Didn't change the overall 
behavior though... :(

I know that if I didn't follow through with the makes my system would have 
been completely crippled since some libs had been recompiled and 
installed, whereas others had not been because 6.0 features a different 
version of gcc and libc than 6.1 does.

If you could provide a command which corrects the spwd.db and pwd.db 
files, I think that will allow me to permanently set my shell to /bin/csh, 
which will allow me to login and start fixing my machine from something 
other than single-user mode.

TIA again,
