How do I find a missing object when a load fails?

[Ernest Adams]

Pardon the wildly new'n'ignorant question... I'm just putting EMACS up
on my new ESIX (~= ATT System V/386) for the first time, and when I
try to link temacs, ld complains that one of my libraries (*not* one
of the EMACS objects!?) is referring to symbols which can't be found.
I'm sure they're on the system somewhere... how can I find out which
library a given symbol is in?  I don't have man pages, but I logged into
a public access UNIX and looked up the missing symbols there; they're all
legit, but the man pages don't tell the names of the libraries themselves.
How do I find them?
