Thanks, I knew about "use lib" for my own lib paths, just never tried to have a CPAN module like DBI in my own path.
I just did a manual make of DBI from source, all the files are in the usual blib directory, I'm thinking that if I put everything of blib (except the docs) as part of my distribution (keeping the same structure like: lib/auto, lib/Bundle, lib/DBD, etc.) it should all work. I guess I'll just go ahead and do that, and report back.
Update Yes, it's as simple as that, I took the blib/lib directory, and moved it somewhere, and just do "use lib" to point there, all worked fine.
