Install rpmbuild On CentOS Linux

I have been working on setting up some new CentOS Linux servers for a company I work for and one of the things I need to do is build a more current version of Ruby than what is available in the YUM repositories. To do this I am going to download an updated version of the Ruby Source RPM built for Fedora and then build the RPM’s from that.

The issue is the fact that the path and/or filename exceeded the 260 characters which is set by WinRAR. Below I show some output from the errors received as well as two tips that should help resolve the problem.
