Subject: Test BASERUBY: Ruby 1.9.3 on Travis

We have no clear assertion or check of BASERUBY requirement.
I want to make the current situation more explicit.

I'm NOT saying we should support Ruby 1.9.3 here,
but I'm just checking the situation as per 05bc14d81a1d7f6af826a92371aeff0c3fb2a67e.

FYI, at this moment Ruby 1.8.7 did not work with this Travis config, like:
