Installing ruby-xslt gem on CentOS 5.2

Ruby-xlst is one of those gems that has been known to throw curve balls during the installation process. This is usually because the gem has dependencies on libraries that are typically not installed on a system by default. On CentoOS 5.2 the following sequence of commands should do the trick

$> yum install libxml2-devel libxslt libxslt-devel

$> gem install ruby-xslt

The first command uses yum to installed the required libxml2 and libxslt libraries. Once this is done, you can then install the gem.
