Thanks guys. It turns out the fix was to delete every Ruby-related thing I could find on my machine and then reinstall what I wanted using RVM. I posted it as a bug rather than on the help forum the way it was crashing made me suspect that there might be some deeper problem going on. Yusuke, I was indeed using the 1.9 interpreter with RubyGems 1.8. ---------------------------------------- Bug #6325: Can't install https://bugs.ruby-lang.org/issues/6325#change-26058 Author: flowshine (Kurt von Laven) Status: Feedback Priority: Normal Assignee: Category: Target version: ruby -v: ruby 1.9.3p125 (2012-02-16 revision 34643) [x86_64-linux] I am trying to install RubyGems 1.8.22 and Rails 3.2.3 on Red Hat 4.4.6-3. I used RVM, and the precise sequence of commands is attached as well as my ~/.bashrc file. Evidently my installation didn't work.
