If no additional new modules are allowed, then you're stuffed. However, what you probably meant is that you can't get any modules installed *in the default location*, in which case the solution is obvious. Install them somewhere in your home directory and set PERL5LIB appropriately.

Did you actually read this post and the link provided before replying? If so what problems do you have, is there anything you don't understand? Unless you tell people what you are having problems with, repeated requests for help aren't going to do much good.
I did read the post. But after I untar all things and attemp to install, I am stuck at "fetching with the LWP...", seem I am behind a firewall, I thought there is no need to use internet since I already downloaded the package.
There are links to eleventy million pages explaining how to install modules in your home dir here. Of them all, these days I recommend using local::lib. At least, I do on Unix. No idea how well it works on Windows.
To install without internet access you'll need to get the distribution (the Some-Module-1.234.tar.gz) file or its contents onto the machine. Untar it, then ...
Adjust as necessary for other CPAN clients. These days cpanminus is probably the best choice.
Installing dependencies can be a gigantic pain in the arse if you don't have internet access (or you don't have a copy of the CPAN already on the target machine). If you have lots of dependencies, then I suggest that you build another machine similar to the target - same OS, same word length - which could be a virtual machine on your desktop which *does* have internet access, and build all your modules there. Once that's done, copy the results to the target machine and hope for the best.
