Thanks for your help guys, here is the article:

[MacRuby-devel] [MacRuby] #555: Redefinition of method gives unexpected behavior

#555: Redefinition of method gives unexpected behavior

 Reporter:  macch...@…  |   Owner:  lsansone...@…

 When I run following test program with Ruby 1.9.1/1.8.7 and MacRuby 0.5b2
 I get an unexpected result:

 {{{
 class TestClass
   def initialize; @a_var = "content"; end
 end

 a = TestClass.new; puts "a: %s" % a.inspect

 class TestClass
   def initialize(k); @a_var = k; end
 end

 b = TestClass.new "valueGiven"; puts "b: %s" % b.inspect

 c = TestClass.new; puts "c: %s" % c.inspect
 }}}

 results in Ruby 1.9.1/1.8.7 with the expected behavior:

 {{{
 a: #
 b: #
 initTest.rb:13:in `initialize': wrong number of arguments (0 for 1)
 (ArgumentError)
 from initTest.rb:13:in `new'
 from initTest.rb:13
 }}}

 In MacRuby I get following output:

 {{{
 a: ##-
 b: ##-
 c: ##-
 }}}

 It seems that {{{#initialize}}} (without arguments) is still floating
 around...

 Whoops, probably my bad.  I assume this is with the latest nightly?

 If you could write this failure up as a spec, that would be awesome. If
 not, I'll try to get to it tomorrow.

 lib_file =
 File.join(File.expand_path($0).slice(0,File.expand_path($0).index("dmdnlib")),

 require "#{lib_file}"

 The result from this is students-v-ldap.rb:in `': no such file to
 load /Volumes/DMDNTech/scripts/ruby/dmdnlib/lib/lib.rb (LoadError)

 I have tried to load said lib.rb by requiring in macirb with an explicit
 path.

 irb(main):002:0> require '/Volumes/DMDNTech/scripts/ruby/dmdnlib/lib/lib'
 LoadError: no such file to load --
 /Volumes/DMDNTech/scripts/ruby/dmdnlib/lib/lib.rb

 macruby /Volumes/DMDNTech/scripts/ruby/dmdnlib/lib/lib.rb runs without any
 errors...

 I need this to work as lib.rb apart from some globals puts all of my
 library folders into the load path.

 Dir.glob("#{$DMDN_ENV[:root]}/**/**").each do |f|
   next if !File.directory?(f)
   next if f =~ /\.app/
   $LOAD_PATH << f
 end

 I then only ever need to use require 'x' instead of an explicit path.
