What next: Text_Wiki and Text_Wiki_Mediawiki

I am trying so hard to set up a Wiki and am at teh stage of setting up Pear, following the docs:
http://cvs.drupal.org/viewvc.py/drupal/contributions/modules/pearwiki_fi...

Firstly, I am do not understand this command line n or how to use it
cvs -d :pserver:cvsread@cvs.php.net:/repository checkout -d Text pear/Text_Wiki/Text

So I went to the source and downloaded both Text_Wiki and Text_Wiki_Mediawiki

The rest was a guess that I must have gotten wrong:

I took the "Text" directory from Text_Wiki_Mediawiki and put it into modules/pearwiki_filter/

I now have the apparently required file path.

When I try to create a node using Mediawiki markup, I am told

"Loading of Text_Wiki class from PEAR failed."

Like I said, I guess I got something wrong when defining my filters, even though all was ok in the filter configuration.

My suppoirt requests:

1. what did I do wrong
2. what do I do with the directory Text_Wiki? I notice that it also has a subdirectory called "Text"
