PHPUnit installed but simply doing nothing - macos

Question

I am following along with the tutorials in 'Easy PHP Websites with Zend Framework' and wanted to install PHPUnit.
System: Mac OS x Lion, PHP running locally (Not MAMP)
Pear was installed and working fine, I upgraded it to the latest.
Installed PHPUnit using
sudo pear install phpunit/PHPUnit
terminal did some work and installed it without errors
The in my terminal I did
phpunit --version
this returns/does nothing as follows (Username removed)
Machine:~ Username$ phpunit --version
Machine:~ Username$ sudo phpunit --version
Machine:~ Username$
Was worried it some how did not install so I check for the PHPUnit files and they do exist under /usr/lib/php/phpunit
Also checked that the phpunit exe exists which it does under /usr/bin
edited .profile as well as .bash_profile to include the /usr/bin path to have
export PATH=/usr/bin:$PATH
then restarted terminal
running
echo $PATH
shows
/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/local/git/bin:/Users/xxxxx/development/frameworks/ZendFramework-1.11.11/bin
php.ini includes is
include_path = ".:/usr/lib/php/pear:/Library/Server/Web/Data/Sites/ZendFramework-1.11.11/library"
Where xxxxx is my username on the Mac
even going into /usr/bin in terminal and using phpunit --version returns nothing
in case its relevant my PEAR config shows
Configuration (channel pear.php.net):
=====================================
...
...
PEAR executables directory bin_dir /usr/bin
PEAR documentation directory doc_dir /usr/lib/php/doc
PHP extension directory ext_dir /usr/lib/php/extensions/.....
PEAR directory php_dir /usr/lib/php
PEAR data directory data_dir /usr/lib/php/data
PHP CLI/CGI binary php_bin /usr/bin/php
php.ini location php_ini <not set>
....
....
PEAR Installer temp directory temp_dir /private/tmp/pear/temp
PEAR test directory test_dir /usr/lib/php/test
PEAR www files directory www_dir /usr/lib/php/htdocs
....
Also added the pear and phpunit directory to my php.ini includes path list.
Am at a loss as to why this does not want to work. Am sure its me and I have done something incorrectly....Any help appreciated.

Answer 1

Ok, solved this, finally after much reading and fiddling. Issue was with PEAR, not PHPUnit itself.
Found the issue by following the set up for PEAR onhttp://pear.php.net/manual/en/installation.checking.php
php.ini change from
.:/usr/lib/php/pear:/Library/Server/Web/Data/Sites/ZendFramework-1.11.11/library:/usr/lib/php/PHPUnit
to
.:/usr/lib/php/pear:/Library/Server/Web/Data/Sites/ZendFramework-1.11.11/library:/usr/lib/php
solved this issue immediately.
phpunit --version now works
