First,

>> str = 'blah'
=> "blah"
>> old_str = str
=> "blah"
>> str << 'test'
=> "blahtest"
>> str
=> "blahtest"
>> old_str
=> "blahtest"

Maybe you mean ENV['path'] += ENV['PW_PATH'], or maybe you mean
old_path = ENV['path'].dup

Second, paths have separators, so simply sticking two different path
strings together is going to make something strange at the join.

Third, I think you mean ENV['PATH'], not ENV['path'].
