Addressing the last part of your reply, first: I did not say I "don't know FrontPage;" I said, loosely translated, that I don't like it because the code it produces is non-compliant with w3c standards, filled with proprietary bloat, and exceedingly difficult to transform to anything which does meet my standards. Your standards may vary, but please don't twist my words.
Your observation that "FP isn't reading the (original) Config.pm file as if it was some native module, it's just creating metadata about the Config.pm file, and saving it in a directory called..." seems, in the context your two nodes now provide, to suggest that FP has access to Config.pm... which rings warning bells to me.
"Limited??" - Yes. Still. No clear statement of OS; no hint of which server software (Apache, IIS, something else?) you're concerned with. And in light of your reply, I'm not even sure if the phrase "hosting accounts" has the same meaning to you that I initially initially credited it with meaning.
And, finally, your so-called "... bare-bones example script...." illustrates very little of any consequence (except, perhaps, the use lib qw(./lib); suggesting a *n*x-ish OS).
