Current I am trying to install phpunit on my mac os x and mamp server:

pear config-set auto_discover 1
pear install pear.phpunit.de/PHPUnit

Errors which I got during installation:

Validation Error: This package.xml requires PEAR version 1.9.4 to parse properly, we are version 1.9.2

pear upgrade pear

Nothing to upgrade

UPDATE 1

This is my pear config. I assume that I messed up local and mamp installs(I didn't know that mamp also has pear, so I installed local one).

I suppose something wrong with bin_dir, php_dir and other paths?
