Currently I have PEAR v1.9.4 installed.

If I perform pear list -a I see:

PHPUnit_Selenium   1.2.8   stable

in the middle of the response. While the latest version is 1.2.11.

I've already updated the channel using:

pear channel-update

but still - for sudo pear upgrade I get

phpunit/PHPUnit_Selenium is already installed and is the same as the released version 1.2.8
upgrade failed

What am I missing?
