Downgrading from latest master to 0.6.0, unable to compile

[Chuongv]

I originally compiled cargo from source successfully, a few days back off of master. Now I am trying to downgrade to 0.6.0 to since I was having issues with one project, thought that maybe going down would help.

I also originally had rust on latest master, then I went back to the stable branch. Not sure if that matters.

What's weird is that I also wasn't able to do make test on latest master either for cargo.

Seems to be similar to alexcrichton/ssh2-rs#23

brew install libssh2
brew install openssl
brew link --force openssl

But still get the same error.

This basically indicates that the project was compiled against one OpenSSL version and then linked against another. That happens here because compilation uses the homebrew-based OpenSSL but then linking (which picks up /usr/lib via a zlib dependency) ends up using the system OpenSSL, a much older version.

You may have to start out from a new clean build directory if you're using a system libssh2 instead of building one from scratch as well, but that in theory should do the trick!

Thanks!

For anyone curious on how to solve this:

make clean
brew link --force openssl

Which should let you build again.
