When you install php-channel-phpunit-1.3-7.mbs2.noarch.rpm you are in fact installing pear.symfony-project.com, which makes install/registering pear packages fail.

Somehow the php-channel-phpunit-1.3-7.mga2.src.rpm and php-channel-phpunit-1.3-7.mbs2.noarch.rpm differs. The source rpm is correct but the binary rpm is wrong:

[root@localhost /]# cat /usr/share/pear/packages/pear.phpunit.de.xml

            </rest>

    </servers>


After further investigation php-pear-channel-horde-1.0-15.mbs2 and php-pear-channel-components-1.0.0-2.mbs2.noarch.rpm are also affected.

I suspect the mageia build system / file storage is to blame for this as the affected source rpm packages shares the "channel.xml" file name for Source0:. This makes me quite worried what else may be affected in mga2 (and later?), and no one else noticed?
