This is a simple problem to fix ... You need to move the DebianNet.pm file and the Debian and Dpkg directories from under the Perl 5.005_03 library tree (eg. /usr/lib/perl5/) to that of the new Perl 5.6.1 library tree (eg. /usr/local/lib/perl5/5.6.1). To check your relative @INC paths (and help fathom what is going on with the Debian tools and their errors), the following code is useful:

perl5.00503 -e 'print join("\n", @INC), "\n"'
perl5.6.1 -e 'print join("\n", @INC), "\n"'

Unfortunately I moved my Debian packages a long time ago, else I could give you the exact mv command ... Oh well *grin*

 

Ooohhh, Rob no beer function well without!
