BTW, the order can also be changed at build time. I don't know how
to do this, but I haven't searched closely...

Also, a 7-year-old thread on @INC search order was resurrected
a couple of weeks ago:

Concerning the man pages, I'm not so sure. As I've said in another
mail, the suffix (a.k.a. man section) is different, meaning that
there would be no conflicts, but this may depend on the modules.
