I've tried to create a simple RPM using the logstash 1.4.2 tarball and have been unsuccessful in eliminating the following auto-dependencies that rpmbuild has placed on my package. Not sure why it would require the following, seeing as how it is all inclusive. What concerns me is the jbruby and ruby references.
Requires: /bin/bash /bin/sh /home/jls/.rvm/rubies/jruby-1.7.12/bin/jruby /usr/bin/env /usr/bin/ruby
I've included the spec file, it's really quite simple. I'm pretty sure I'm missing something small.
