Error: dlopen ... Symbol not found

[Matthew]

Hello,

I'm building my first node addon, which includes bindings for Berkeley
XML DB. The addon builds fine (on OS X 10.6) but when I try and run a
test js file, I get the follow error - any idea why?

$ node test.js

module:318
process.dlopen(filename, this.exports);
^
Error: dlopen(/Users/mattcg/Source/node_dbxml/binding.node, 1): Symbol

Is the code on github or someplace? If you send a link, you'll
probably get more help.

Did you get this resolved? I'm running into the same error myself now
on a different addon.

Oh, I figured this out.

For the next traveler who comes looking:

The constructor template has to be declared at the top-level scope.
For example:
