Make sure you have wolfSSL built with the --enable-ssh option in configure. It sets the the WOLFSSL_PUBLIC_MP flag which should add those missing functions to the wolfSSL public API.
@BrianAker is using the Homebrew install of wolfSSL which doesn't enable the wolfSSH build option. wolfSSH currently needs the mp_int public interface for an ECDSA signature check. It doesn't, it can wolfCrypt ECC public APIs.
I tested #475 with a copy of wolfSSL with public-MP disabled. It built fine. When I used the Homebrew install of wolfSSL, I had to fix a warning about an unused variable which PR #476 takes care of.
I'm closing this issue at this time.
