Uh, huh.  How about all that platform specific code that doesn't get
loaded?  E.g. Module::Build::Platform::VMS.  The same kind of platform
specific stuff happens elsewhere, like Devel::CheckOS.  So it's never
just a matter of seeing what loads and bundling that.  There are
always going to be heuristics to figure out the complete set of things
to bundle.

Having an 02packages file from a CPAN to map from a requested module
to a distribution and then interrogating the distribution metadata is,
in my opinion, the most robust way to do this.

I think requiring a distribution author to have a CPAN handy is a
really, really low bar.
