Thanks for the report. I fixed most of these, as well as the configure 
tests for bundles/constructors, etc.  Unfortunately, bundles still 
don't seem to work as classes don't appear to be automatically loaded 
into the runtime when the bundles is loaded in.  I'll have to dig 
deeper into how that works on darwin.
