What version of the product are you using? On what operating system?

Tests fail from r102 to r130, last working tests appears to be r101
PHP 5.3.1 on MacBook, Darwin Kernel Version 10.3.0

Please provide any additional information below.

I'm assuming the tests do not require updated schema to support oauth_verifier. 
All tests were run against a schema created from an r98 download.
