A bit ago I needed to install Subversion on CENTOS. With the particular provider setup it didn't quite work as expected. The simple yum -y install subversion didn't work because it needed a newer perl(URI) version. More annoyingly cPanel didn't report that the installation failed or that the problem was. Luckily Google had the answer in this wiki page which provided step by step directions to installation. Though it still doesn't make cPanel any more enjoyable at least this tie it didn't get in the way too much.
