The library doesn't have a file called ib.rb, and/or the library's lib
directory is not in your $LOAD_PATH.

Try:

irb -I ib-ruby/trunk
require 'datatypes'

Or:

···

$:.unshift 'ib-ruby/trunk'
require 'datatypes'

Well, I only suggested require 'datatypes' because you showed
datatypes.rb as the only file checked out.

Looking on rubyforge, I see there are others. There is an examples/
directory. Use it. The examples say

require 'ib'

rather than

require 'datatypes'

(and I see that ib.rb in turn requires iblogger.rb)

irb(main):001:0> $:.unshift 'ib-ruby/trunk'
irb(main):002:0> require 'ib'
=> true
irb(main):005:0> ib = IB::IB.new()
=> #<IB::IB:0xb7638e10

option 1: start your session with

  irb -Iib-ruby/trunk

option 2: put the $:.unshift 'ib-ruby/trunk' into a file called boot.rb,
then you just do require 'boot' before require 'ib'

option 3: install the ib gem (and then require 'rubygems'; require 'ib')

option 4: put the session setup into ~/.irbrc [not recommended, you
don't want all your sessions to have this]

option 5: copy all the ib code into the current directory [messy]

If you are building an application, I would be inclined to make a
vendor/ subdirectory and install ib under that, and have a boot.rb which
adds it to $:. Your app just needs require 'boot' at the top.
