Your scripts do use these >perl modules, and so they do depend on them. I rarely find myself disagreeing with you, but this is one of the times. I have encountered times when the auto dependency stuff picks up instances of use Foo::Bar; inside a perldoc section. There are also lots of cases where "dependency" is too strong a word. For example, I've installed and used the perl-libwww module for years, and it wasn't until trying to build it on Red Hat ES 3 that I discovered that there are parts of it that need HTML::Parser and Font::ATM to work. There are also perl modules that can detect, at runtime, whether a module is present, and work around its abscence, sometimes with reduced functionality. > Its easy to grab the cpan >modules you are depending on, and then run them against cpanflute2 (found >in the RPM::Specfile cpan module), That's fine for simple modules with modest requirements, but it gets to be a huge PITA for some of the more esoteric modules. I've spent entire evenings tracking down ever growing chains of perl module dependencies, just to get one module installed that only needs its dependencies for 10% of optional functionality. I think auto dependency detection is a good thing, it's just that the way perl handles modules and the "optional but recommended" nature of some module dependencies doesn't mesh well with RPM's notion of "required".
