Not to sound flippant or anything (I'm genuinely interested) -- why would you want to do this? It would involve either sprinkling copious amounts of use lib around, or working with a horrendeously long @INC.
I want to set the PERL5LIB path in the apache itself and more over I run multiple perl projects ...so portablity is high in that case.since I just copy only that particular folder and happly carried out anywhere without any dependencies !!!
I agree that what you're saying.
How you're collecting custom modules ?? . I guess, you're copying required modules from the perl default path after PPM was installed if i'm not wrong. My question is why should I copy from the base instead of directly point it to where we want.
