Maybe I'm missing something (I haven't been paying very close attention
to this thread), but if you request an ancient version of spiffy it's
probably not going to work with the latest intarweb.  The meta files
can't express this, because that would be knowing what future versions
of an extension will break your code.

Bundler has fancy ways of specifying exactly what version of each egg
you want, but IIRC by default it just "nails down" the exact versions
you have installed right now.  This means you get an easy way to
reproduce the exact current situation.

Cheers,
Peter
