Following error occurs every time start any bitcoin command

Did you build Bitcoind with Homebrew's OpenSSL? In which case, We killed off SSLv2 a couple of months back completely, using the same method Debian/Ubuntu/Arch/etc do. That'll be why you're seeing this message.

So homebrew's openssl dependency is incorrect?
DomT4 commented at 6:58 PM on October 26, 2014: contributor

In what sense?

Bitcoin from the next version will be configured without SSLv2, per this commit.

How & when did you build bitcoind? Unless you built it several months ago and haven't rebuilt it since then you shouldn't encounter this error. Your error message seems to hint that you installed it a fair while ago, because anything built with our newer OpenSSL wouldn't hit this error because bitcoind wouldn't expect to see SSLv2 available.

The issue starts repro about week ago. Today i pull master again and repeat steps described into your REAMDE

I'm not sure why this would affect bitcoind. SSLv2_client_method should be a weak symbol there. At the very least the problem should go away after a recompile against the newer libssl, but I'm curious as to why you'd see it in the first place.

Ah, It comes from boost. Looking into this now.
theuni commented at 7:39 PM on October 26, 2014: member

Please try this: ./configure CPPFLAGS="-DOPENSSL_NO_SSL2". OpenSSL and Boost both respect that define.

That should work for you, and should solve a few of our problems at once, actually. I'll work on a patch to hard-code this into our build.

Using ./configure CPPFLAGS="-DOPENSSL_NO_SSL2" got problem with make
```
Making all in src
make[1]: Nothing to be done for `all-am'.
```
theuni commented at 6:39 PM on October 27, 2014: member

That's not a problem, it just means that your binaries have already been built. 'make clean' then 'make' again.

the same issue, i'll wait for new release((
theuni commented at 10:36 PM on October 27, 2014: member

What is the "same issue"? If your program still crashes, it will likely crash in the next release as well if we don't track down the issue. Please use ./configure CPPFLAGS="-DOPENSSL_NO_SSL2" && make clean && make and report back with the results.
