are all statements in your post, commands that I should enter at the command line?

I forget, I think they're links you can click and read and decide what you want to do, or try them out

What do you mean by "add"? where do I have to add it?

I don't know, sorry, it would certainly be in the documentation -- although you don't have to, given that you can install by giving a full url

are these commands that I should use with the StrawberryPerl PPM utility, or did you assume I was running ActivePerl?

I don't know; I gave you some choices, I know you've used ppm before, and at some point you have to try and figure it out

If so, then some instructions there are unclear

Yup, I see that now, links as instrunctions doesn't seem to work :/
