Why does vanitygen warns me to update an up-to-date OpenSSL? I tried to generate an address with vanitygen. Because I'm on a MBP 2010 it took a while onthe CPU (not finished yet, two times up to 20%) and now I am trying to get it working with my GPU (NVidea 330m). That works, it is three times as fast as the CPU (±750 kkeys/s vs 230 kkeys/s), but I have a question about the OpenSSL. 

When I start oclvanitygen ./oclvanitygen -d 1 -i 1Mathias it gives me the following warning:

WARNING: Built with OpenSSL 0.9.8y 5 Feb 2013
WARNING: Use OpenSSL 1.0.0d+ for best performance


However, openssl version gives me this:

OpenSSL 1.0.1h 5 Jun 2014


And sudo port upgrade openssl returns also that there is nothing to be done. How is this possible?
You might want to try WyseNynja's Homebrew tap, you can then install vanitygen with better dependency handling.
