That normally means that your fragment *imports* something that is not
exported. Do a DumpPEF on the fragment and check what it is importing from
perl. It might be that I forgot to export some of it from MacPerl.

That's why they call it a bootstrap function :-)

Perl gets the bootstrap function through a lookup by name and calls it. This
function then registers all the other exported functions (and since it resides
in the same module, it can reference them locally without needing to import
them.
