xml-dom package installation for PERL

[kelly]

hallo, i have a problem about the xml-dom package installation for PERL. i downloaded a xml-dom.ppd from Perl5.6 repository because i am using Perl5.6.1 now....and then i use PPM2.1.6 version to install it, and came the messages below:

Installing package 'd:\inetpub\chen\backup\xml-dom.ppd'...
mkdir C:\DOKUME~1\fkessel\LOKALE~1: File exists at D:/Programme/Perl/site/lib/PPM.pm line 314

after that, i cannot use the package still.....

is there anybody can tell me why????thank you....
