Incorrect shared libraries picked in AIX - aix

Question

While building a particular module, I get the below error:
ld: 0711-317 ERROR: Undefined symbol: .MD5_Init
ld: 0711-317 ERROR: Undefined symbol: .SHA1_Init

I see that these symbols come from openssl's libcrypto.a library:-
$ nm openssl-1.0.2f/libcrypto.so|grep SHA512_Final
.SHA512_Final T 448
SHA512_Final D 3088 24
SHA512_Final d 2976 8
.SHA512_Final U -
I have exported LIBPATH=:$LIBPATH and built with -lcrypto option. However from the dump output, I still do not find the libcrypto.so from openssl being used from ldd output.

While the build has passed, the output from ldd still is quite perplexing.
1. Why does libcrypto.so not appear as a dependency in ldd?
2. However, how is the dependency for the symbols listed above being resolved by the linker?
