I'm not sure how base has evolved over the years, but I've had problems where it died complaining it couldn't locate a module where the package was inline in the script further down, and it may indeed load an unwanted module of the same name (B is a favourite example) under similar circumstances. Fun for the whole family.

Checking $VERSION in a package, to check if the package exists, is not the best way to tackle the problems, IMO.
