difficulty with phpDocumentor

I'm trying to use phpDocumentor and am having some difficulty. I first download PHP 5.1.4 and type go-pear from the directory it's been placed in. I hit enter four times and then run the resultant PEAR_ENV.reg. I close the command window and reopen it. In this new command window, I type "pear remote-list". After a long delay, I get a list. I then type "pear install phpDocumentor". It works. I then type "phpdoc -h" and I get the following output: Warning: include(PhpDocumentor/phpDocumentor/phpdoc.inc): failed to open stream: No such file or directory in C:\games\dev\pear\php3\phpdoc on line 37 Warning: include(): Failed opening 'PhpDocumentor/phpDocumentor/phpdoc.inc' for inclusion (include_path='.;C:\php5\pear') in C:\games\dev\pear\php3\phpdoc on line 37 Any ideas as to what the problem is???
