Spellcheck & RedHat OpenSSL fix

[mboman]

The following unified diff fixes two issues:

1. Redhat (and CentOS) OpenSSL does not include Elliptic Curve crypto. This patch only checks EC crypto if it is available.
2. The word "Preferred" was misspelled.

I am not familiar with git and "git push" didn't work for me so I've attached it here.
