Will installation of macports automatically install or update OpenSSL?

I am a mac user and want to stay with the system-provided version of OpenSSL, which is OpenSSL 0.9.8y. I am wondering if installation of macports will automatically update my OpenSSL or install another version? Also, how can I check the version of the OpenSSL library on my mac instead of the version of the OpenSSL command? Do they always have the same version? Thanks!
