I got the following error with a "svn" command:
OpenSSL version mismatch. Built against 1000105f, you have 10001060
svn: E210002: Unable to connect to a repository at URL 'svn+ssh://mysvn'
svn: E210002: To better debug SSH connection problems, remove the -q option from 'ssh' in the [tunnels] section of your Subversion configuration file.
svn: E210002: Network connection closed unexpectedly
It was not clear that the error came from ssh (in particular since svn
is linked against libssl, but not ssh). Like most commands, ssh should
output the process name before the error message, e.g.
ssh: OpenSSL version mismatch. Built against 1000105f, you have 10001060
