The Xtras package in Xtreams uses libcrypto. The EVP_MD_CTX_init error 
is saying that the FFI call to the libcrypto library that comes with 
OpenSSH cannot be found. This library is used by Altitude to generate 
random URLs.

Open your Terminal and "man openssl" to see if you have libcrypto. I 
think it comes standard on a Mac. If that's the case, then perhaps your 
FFI cannot make the call to the library.
