|No such thing as a small change|
Without being too rude the whole idea of this tutorial was to teach you how to install a Module by hand. PPM and CPAN are convenience tools. Like all tools they have issues. You have just found one.
Go to search.cpan.org. Type in Win32::RASE, search, download the module, extract it (winzip will do). While you are there type in 'enum' - this is another module (enum.pm), so do likewise - download and extract it as well.
Now get a command prompt. Navigate to dir where you extracted the modules to (I extract into c:\temp) so cd c:\temp\[module name] will do it. Follow instructions above ie perl Makefile && nmake && nmake test && nmake install
If you try to do RASE first you will note it says it needs enum.pm (that's why you got it) so do that first and RASE second. It is very easy and should take no more that a couple of minutes.
If you want the docs (from the pod) to appear in the ActiveState docs do one of these after you have installed the modules.
