Yes, the problem you pose is very well solvable (see below), but ... 
what exactly are you trying to accomplish by dynamically defining named 
local variables?

A wise Rubyist once said "eval is evil", so beware!

>> array = %w[a b c]
=> ["a", "b", "c"]
>> array.map {|x| "#{x} = Object.new" }
=> ["a = Object.new", "b = Object.new", "c = Object.new"]
>> array.map {|x| "#{x} = Object.new" }.join('; ')
=> "a = Object.new; b = Object.new; c = Object.new"
>> eval array.map {|x| "#{x} = Object.new" }.join('; ')
=> #<Object:0xb7d74fbc>
>> a
=> #<Object:0xb7d74fe4>
>> b
=> #<Object:0xb7d74fd0>
>> c
=> #<Object:0xb7d74fbc>
