Require statement not working in ruby from bash - ruby

Question

I'm trying to get ttscoff's TaskPaper to Markdown ruby script https://gist.github.com/511174 working. However, I use rvm, which seems to present some challenges.
-rjcode is a no-longer needed Unicode flag and -Ku is another encoding flag I can probably ignore.
I found instructions for adding rvm as a function to your script, but the script still errors as soon as it hits require ftools.
What I added is:
#!/usr/bin/env bash
# TaskPaper to Markdown converter
# Usage: tp2md.rb filename.taskpaper > output.md
# Load RVM into a shell session *as a function*
# Load RVM into a shell session *as a function*
if [[ -s "$HOME/.rvm/scripts/rvm" ]] ; then
# First try to load from a user install
source "$HOME/.rvm/scripts/rvm"
elif [[ -s "/usr/local/rvm/scripts/rvm" ]] ; then
# Then try to load from a root install
source "/usr/local/rvm/scripts/rvm"
else
printf "ERROR: An RVM installation was not found.\n"
fi
# Configure ruby and gemset
rvm ruby-1.9.2-p290#global
ruby <<-rb
puts "Hello!"
rb
Hello! outputs fine, but I get the following errors afterwards:
require: command not found
infile: command not found
prevlevel: command not found
begin: command not found
syntax error near unexpected token `('
` file = File.new(infile, "r")'
My problem seems to be related to the gem not getting pulled in. I've uninstalled ftools and reinstalled with rvm, but still no dice. Thankful for any help!

Your telling ruby to load the 'b' library.
-r library Causes Ruby to load the library using require. It is useful when using -n or -p.
This should work.
ruby -r ftools <<rb
puts "Hello!"
rb
