Unable to complete test on iphone4 with Mac Book Pro running Yosmite

Hi All,

Trying to get a test running on iphone 4 jail broken running ios 7.2 as the client and Macbook pro as the host running OS Yosmite, i am running into the below response when the test is submitted from the WPT server. Looks like i am unable to get the library loaded.

Does anyone have any thoughts on how this can be fixed?
