svn: E155021: This client is too old to work with the working copy at - Finding the executable path in MAC OS X

Got this error ON MAC OS X but you believe you have available the right version?

svn: E155021: This client is too old to work with the working copy at

First look at how many svn

$ which -a svn
/usr/local/bin/svn
/usr/bin/svn
/usr/local/bin/svn

Look at the output for each of the output using the --version flag. You might notice that the default which output is not the same as the default command output:

$ command -v svn
/usr/bin/svn
$ which svn
/usr/local/bin/svn

You might be tempted to update some symlinks or your PATH variable but before doing so try from a new console, it might be just that you are hitting a console open before you installed the latest version.
