phpdocumentor under php5 error!

[Yarco]

I have just installed phpdocumentor on using:

pear.bat install phpdocumentor-beta

to suitable my php version.

Then i create a test file "test.php" to have a trial.
But the result is:
E:\yarco\workshop\web\php>phpdoc.bat -f test.php -pp on -s on -o
HTML:frames:default -t test
PHP Warning: main(PhpDocumentor/phpDocumentor/phpdoc.inc): failed to
open stream: No such file or directory in
D:\unix\usr\local\lib\PEAR\phpdoc on line 39

So, i add:
chdir('D:\unix\usr\local\lib\PEAR\pear');
into phpdoc.

I run:
E:\yarco\workshop\web\php>phpdoc.bat -f test.php -pp on -s on -o
HTML:frames:default -t E:\yarco\workshop\web\php\test

But get the following errors:
PHP Version 5.1.0RC1
phpDocumentor version 1.3.0RC3
