I have already tried everything, including https://stackoverflow.com/a/8740349/251311 and all possible channel upgrade and clear cache commands. But still:
$ sudo pear install -a -f phpunit/PHPUnit

There will be 100 points bounty for a person who will hint what can cause PEAR not be able to upgrade phpunit to the latest possible (using PEAR).
Well, I use ubuntu lts 10.04, and it has php 5.3.2 version.
While phpunit 3.7 depends on php >= 5.3.3 (though it’s not shown explicitly anywhere)
