testsuite: 143 failed on OS X 10.8.2

[Samuel John]

Hi,

On latest Mac OS X 10.8.2 (aka Mountain Lion) the testsuite: 143 failed.

I am in the process of updating the Homebrew [1] formula to version 2.7.
Therefore, I ran the testsuite[2]. The configure output is also in the same 
gist https://gist.github.com/4335706.
Is this failure a show stopper for us to update?
