Hello, thanks for building this Rust driver, I appreciate it!

Just wanted to let you know, I'm facing an error when I try to install it using Cargo. Here's the output of the cargo install rsmgclient invocation:

From looking at build.rs, it looks like this crate expects OpenSSL to be installed on macOS using Homebrew. There should probably be a way to set this using an environment variable like OPENSSL_PATH. We could also make it more robust by checking for MacPorts installations.

I've submitted a PR to add supports for MacPorts: #41 .
