Can't seem to get bundler working with rails 2.3

Question

I am on rails 2.3.5 and ruby 1.8.7

I keep trying to run the bundler command and it doesn't seem to work anymore.

I keep getting

undefined method `[]' for nil:NilClass (NoMethodError)

Here is the trace when running bundler install

Here is what happens when I try to start the server.

Modified the .bundle/config file is what caused this error.
