pdepend, no releases available

Question

I'm trying to install PDepend on my Centos 6.3 server. For some reason I constantly receive an error that there are no packages/releases available.

Things I already executed:

• pear upgrade
• pear clear-cache
• pear channel-discover pear.pdepend.org
• pear install pdepend
• pear install pdepend/PHP_Depend-beta
• pear remote-list -c pdepend

None of them pointing me in any direction. No errors occure except that there are no release available for package "pear.pdepend.org/PHP_Depend"

Strangest part is that I'm succesfull with installing pdepend on my Ubuntu server. In that case, the first 3 steps are the only ones needed to install pdepend.

Anybody a suggestion how I can install pdepend?
