in reply to Local CPAN settings

Good meditation; I've been there.

As you have observed, some versions of CPAN.pm install config information to a CPAN::Config in everybody's @INC path, in such a way as to prevent non-root users from using CPAN.pm. When this happens, I have removed (or simply moved out of the way) Config.pm, and rerun the configuration dialogue as a non-root user.

As an aside, I have a standard technique for dealing with CPAN on Unix systems. The first stage might be to upgrade the perl if the version is older than I am comfortable with. Otherwise, in most instances, the version of CPAN.pm that the installed Perl ships with is a bit old.

I install curl, ncftp and lynx, as these are tools that CPAN.pm will be asking for. And I install and configure sudo of course if it's not there.

As root, I upgrade CPAN.pm to the latest, going through all the configuration questions installing CPAN and leaving the CPAN shell. Then, as my non-root user I run cpan and go through the questions again, except this time, there are more of them, including questions about make install and ./build install. To these questions I use the sudo form of the command. Once this dialogue is complete, I can install Bundle::CPAN and any other modules I want, painlessly.

    When you say, use the sudo form of the command, can you give an example? Just trying to understand what you are doing.

      OK, I'll paste some excerpts from the dialogue from cpan "o conf init".

      Do you want to use a different make command for 'make install'? Cautious people will probably prefer: su root -c make or sudo make or /path1/to/sudo -u admin_account /path2/to/make or some such. Your choice: [sudo make] ... Do you want to use a different command for './Build install'? Sudo users will probably prefer: su root -c ./Build or sudo ./Build or /path1/to/sudo -u admin_account ./Build or some such. Your choice: [sudo ./Build]

        OK, now I understand, thank you for example! :)
