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?

    Did you compile oclvanitygen yourself (on 5 Feb 2013), or get the binary from somewhere? It may have been compiled (or be statically linked) with a different version than the one you currently have installed. – Nate Eldredge Jul 10 '14 at 16:52
  • I built it myself, yesterday. The source is however not updated in 2 years (github.com/samr7/vanitygen) – Mathias711 Jul 10 '14 at 17:08
  • A quick glance at the source shows that it checks the OPENSSL_VERSION_NUMBER macro, which comes from the header openssl/opensslv.h. I suspect you have an old version of openssl (or at least its headers) installed somewhere. – Nate Eldredge Jul 10 '14 at 17:13
  • I do got an old HDD with an installation from 2011/2012. The last time I booted from there (and probably updated) was a year ago, june 2013. So that IS a possibilities, that it takes the OpenSSL from there. – Mathias711 Jul 10 '14 at 17:19

You might want to try WyseNynja's Homebrew tap, you can then install vanitygen with better dependency handling.
