hello, as this si leagcy code i can't change such things, and also since this working on most machines except for those where i don't have the sudo access. so i am looking for some way where i can include these packages in my @INC. What i have come across is that CPAN.pm , i couldn't find it to change some conf

As you seem to be unwilling to change %ENV, maybe it's now a good time to simply request sudo access on the problematic machines so you can make the necessary changes there?

As an admin I'd be reluctant to grant sudo rights to someone who can't handle %ENV ...
