Newbie help on setting up SlimServer on NSLU2

[Lord Vader]

Hi all!
As a complete newbie I have tried setting up SlimServer on my new NSLU2 with information from

http://www.nslu2-linux.org/wiki/Applications/SlimServer
All works well until I get to the part

"Now edit the file /usr/local/SlimServer_v6.0.2/Bin/build-perl-modules.pl to add some options to the XML Parser, this is because expat is installed in a non-standard location on the slug. (you need to add the XML Parser section)"
then I got this message "# /usr/local/SlimServer_v6.5.0/Bin/build-perl-modules.pl
Can't locate File/Which.pm in @INC (@INC contains: /usr/local/slimserver/CPAN CP
AN /opt/lib/perl5/5.8.8/armv5b-linux /opt/lib/perl5/5.8.8 /opt/lib/perl5/site_pe

BEGIN failed--compilation aborted at /usr/local/SlimServer_v6.5.0/Bin/build-perl

I have absolutely NO IDEAS what to do and how to do it, could PLEASE someone help me out before losing all of my hair??
