To quote perldoc cpan:
The default values defined in the CPAN/Config.pm file can be overridden in a user specific file: CPAN/MyConfig.pm. Such a file is best placed in $HOME/.cpan/CPAN/MyConfig.pm, because $HOME/.cpan is added to the search path of the CPAN module before the use() or require() statements.

The second problem is the @INC. Is there a way to fool a root-installed binary into adding your ~/my-mods to @INC?

Well, you could set PERL5LIB before you run that binary.

Is there a transparent way to globally modify @INC?

What do you mean by "globaly"? For every process run by a specific user? Set PERL5LIB in that user's login script (actual syntax and filename depends on that user's shell).

Update: (Thanks to borisz): meant to write PERL5LIB, wrote PERL5INC instead. Apologies for the bainfart.
