Here is a solution I have seen in the aircrack-ng code.  Might be interesting to see if there is any performance benefit over OpenSSL at this point.

#if defined(__APPLE__) && defined(__MACH__)
	#define COMMON_DIGEST_FOR_OPENSSL
	#include <CommonCrypto/CommonDigest.h>
	#define SHA1 CC_SHA1

	#include <CommonCrypto/CommonHMAC.h>
	#define HMAC CCHmac

#else
	#include <openssl/hmac.h>
	#include <openssl/sha.h>
	// We don't use EVP. Bite me
	#include <openssl/rc4.h>
	#include <openssl/aes.h>
#endif


Thanks,
Erik
