Type Error running feature in Rail's Cucumber
I'm trying to run Cucumber for my Rails application and keep getting this error:
> superclass mismatch for class Point (TypeError)
There's a huge stack trace from this error, but it does not point to anything specific except a missing requirement. Here's the trace:

I found the answer to this problem, it was a class name conflict with the mySQL geoSpatial plug-in and my schema.
I had a class named Point and everything was happy. Then I added (the very cool) geoSpatial plug-in to use mySQL's geo index features. This plug-in also defines a Point class.
The conflict was causing Cucumber to fail.
If you are seeing this error in your own application, look for duplicates!
