Hi Vin,

Currently building QtWebKit with V8 is not supported on trunk, we are in  
transition of removing our external V8 dependency and moving to the V8  
tree shipped with QtScript.

During the transition we ceased to maintain the V8 build, so the V8 bot  
was switched off.
The last QtWebKit version which should certainly work with a git V8 of  
that time is
r78226 (b8202cec14c7af1bfa99e588a7984cef3bc9b00f)

However this is highly experimental, and only intended for  
proof-of-concept usage.

If everything is going like planned, the experimental feature will be  
reintroduced some time next week in trunk, unfortunately only with a qt  
development branch from:

It won't support building with V8.

Support is supposed to work for the modularized Qt 5, but this is an  
experiment so there is no ETA.
