Rake test:mri fails in newer versions of master

Hi,

Context Mac OS X (10.8). rvm but using rvm use system.

On the master of around 30 Oct 2013, I was (and I am still) able to pass
all but 1 of the
test:mri tests, like this

HEAD is now at ceb9b7c... Merge branch 'jruby-1_7'

Tasks: TOP => test:mri => test:mri:int
(See full trace by running task with --trace)

However, when I take the master of recent (just before merging in my
commits for BigMath.log), I see a lot more failures on rake test:mri.

I must be missing something in my context ?

One aspect is that I have rvm installed, but I did reset it to rvm use system
before these 2 test results I am showing here.

Any hints what I may miss in my environment. Interestingly, the Travis
CI
is green
on recent master (e.g. the one with my BigMath.log was all green). So
probably
I miss a gem or library or setting ?

The (long) error log below.

Thanks,

Peter
