Problem with Dynamic Finders in seeds.rb

seeds.rb

# db/seeds.rb
orig = Security.create!(symbol:'NFLX', name:'Overvalued Content Provider')

puts Security.all

puts orig.symbol
s = Security.find_by_symbol(orig.symbol)
puts s.nil? ? "not found" : "found"

s = Security.find(orig.id)
puts s.nil? ? "not found" : "found"

# Output
# Overvalued Content Provider (NFLX)
# NFLX
# not found
# found

I've reproduced this output so far with both SQLite3 and MySQL. Using Rails 3.0.7 and Ruby 1.9.2p0

Eureka... the annotate gem was installed... and within it, is the following code:
module ::ActiveRecord
class Base
def self.method_missing(name, *args)
# ignore this, so unknown/unloaded macros won't cause parsing to fail
end
end
end
