Re: [tor-talk] obfsproxy failure: obfs3

The packaged version of tor complains about support for faster OpenSSL:

Aug 14 15:26:52.000 [notice] Tor 0.2.4.16-rc (git-dcf6b6d7dda9ffbd)
opening log file.
Aug 14 15:26:52.000 [notice] We were built to run on a 64-bit CPU,
with OpenSSL 1.0.1 or later, but with a version of OpenSSL that
apparently lacks accelerated support for the NIST P-224 and P-256
groups. Building openssl with such support (using the
enable-ec_nistp_64_gcc_128 option when configuring it) would make ECDH
much faster.
