ppm is the Perl Package Manager that comes with ActiveState perl. This build of perl is popular for Windows system but is also available for other system.

There are several ways you might have installed your modules. If you post the details you may get more specific answers to your questions.

In general, you should uninstall the modules with the same tool that you used to install them.

If you used the Ubuntu package manager to install an Ubuntu package, then you should probably use the same package manager to uninstall the package. Simply removing the files may work from perl's perspective but it may confuse your package manager, possibly causing problems in the future. I would uninstall the newer package before installing an older one myself, but someone more familiar with the Ubuntu platform may be able to give you shortcuts.

If you installed packages directly from CPAN with the cpan or cpanp commands, the CPAN or CPANPLUS modules or by manually downloading from CPAN and following the install directions, then you can follow the advice given in the first response to your post and its linked documents and posts.
