What are you trying to do?
you mention a bundle file, but then a require 'wbxml.so'?
first of you need to remove extensions from your requires, that breaks
compatibility since OSX uses 'bundle' and Linux/Windows uses 'so' as
extensions for the shared objects.

I've checked your Rakefile:
And you're assuming a lot about the extension (and the extension of it too).
I suggest you take a look at DrNic post about newgem generators
related to building C extensions:

As I commented before, Hoe was not aimed to create gems that bundles
extensions out of the box.
Are you trying to build a native (pre-build) platform specific gem? or
are you trying to include in your gem the C extension?
Human beings, who are almost unique in having the ability to learn from
the experience of others, are also remarkable for their apparent
disinclination to do so.
