use perl modules up front

The old code actually did the same thing, just obfuscated -- since the eval
use wasn't quoted, it used the modules on load. Thus, the error (not to
mentioned the return) was bypassed, and it just failed on load.

But that seems like the right thing to do, really, so just made it clearer
that's what happens.
