remove darwin x86_64 libbel.bundle

[nbargnesi]

Doesn't make sense to include this. It's for a specific version of Ruby
(2.1) expected to be found in /usr/local/lib.

[abargnesi]

Yeah, this bundle linked against the Ruby I built it on. We still need to have a binary for Mac OSX when running on JRuby. JRuby does not build C extensions.

Any other solutions besides removing this entirely?

[abargnesi]

Worth noting that the build failed with JRuby on Mac OSX.

[abargnesi]

We could include a Mac OSX library for Ruby 2.0, Ruby 2.1, and Ruby 2.2 linked against /usr/lib. Would that be sufficient?

[nbargnesi]

On two of my Ruby 2.2 installations (both Macs), library resolution tries to load this particular bundle and fails. Until JRuby is used in earnest, I'd say punt this. For non-JRuby installs, we can rely on the extension being built as needed. I'm continuing to work through problems on this last point as well.

Here's what can happen now:

Let's leave the library in at the moment. I've opened up #76 to track support for the libbel C extension within JRuby / Mac OSX.

This accepted openbel-server PR makes the included binary bundle a lot less noticeable. Now the bundle that gets loaded by openbel-server isn't something from a cloned repository.
