Your problem is hard to pin down since you don't really provide enough information.

It will probably help if you told us the current perl version, and the versions of relevant modules (and possibly the versions of the working perl/modules if they differ from the current ones). Also some example code and/or a clear as possible description of the problem would be handy. See also how (not) to ask a question.

ps: if you have any of this information, just update your post.
