You can search for these at
http://search.cpan.org/ and download the .tar.gz files individually. Once you have the files, extract them with (for example)
tar -zxpvf AppConfig-1.56.tar.gz and cd into the directory. Usually you just run the following:
Code:
perl Makefile.PL
make
make test
make install
Any variations to this are usually in the README or INSTALL file that came with the .tar.gz file. I used this method instead of trying to download the bundle::bugzilla bundle and it works fine.
