right_aws gem not recognized - 503 Service Not Available

[jmackin]

I'm using the right_aws gem for Amazon S3 access in a rails application.

I get a 503 Service Not Available trying to access the website. stderr.log output:

2009-05-26 19:58:21.755 [STDERR] Missing these required gems:
  right_aws  

You're running:
  ruby 1.8.6.111 at /usr/bin/ruby1.8
  rubygems 1.3.2 at /.gem/ruby/1.8, /usr/lib/ruby/gems/1.8

Run `rake gems:install` to install the missing gems.

However, the gem IS installed and it works. I start up WEBrick and access the website no worries at all.

Am I missing something or why does Litespeed intervene?
