I look for missing routines a somewhat brute-force way, but it works.  The  
shell syntax is sh/ksh/bash.  Exactly what I do varies with the exact  
situation, but it is something like:

cd /usr/lib (or your favorite dir containing libraries)
for f in lib*.a
do
    nm $f | grep -q "T _your_function" && echo $f
done

You'll see a list of libraries with the function defined.  Multiple  
libraries because you might have the profiled libraries installed, etc.
