Since .a is basically just a package of individual object files this command 
will list all symbols that are undefined within a single compilation unit. It 
does not mean that the symbols are undefined within the archive. You can see 
that a symbol may be marked as undefined multiple times and then defined 
elsewhere within the archive (the following is from Linux but should be 
similar to OS X):

$ nm -a /tmp/t/usr/local/lib/libvoikko.a |grep 
                 U _ZN9libvoikko9character10SimpleChar7isUpperEw
                 U _ZN9libvoikko9character10SimpleChar7isUpperEw
                 U _ZN9libvoikko9character10SimpleChar7isUpperEw
0000000000000100 T _ZN9libvoikko9character10SimpleChar7isUpperEw
                 U _ZN9libvoikko9character10SimpleChar7isUpperEw
                 U _ZN9libvoikko9character10SimpleChar7isUpperEw
                 U _ZN9libvoikko9character10SimpleChar7isUpperEw

For us to know what really is undefined it is best to look at the linker error 
message. If linker can't find something, it is really missing.

Also check that you list the static archives in correct order. Something was 
said about that on the Apple page you linked to earlier.
