import the package for perl

[kelly]

when i install the xml-dom.ppd with PPM, it comes these messages:

PPM> install xml-dom.ppd
Install package 'xml-dom.ppd?' (y/N): y
Installing package 'xml-dom.ppd'...
Bytes transferred: 74265
Writing D:\Programme\Perl\site\lib\auto\XML\DOM.packlist

is it that i install it successfully?

but when i write

use XML::DOM;

it still cannot find the package....could anybody tell me why?
