Cannot Install using CocoaPods since updated to Xcode 5.1

[mrcrow]

I worked with BlocksKit for a long time and just updated the Xcode to 5.1 these days.
After the updates, some parse issue appears for Pods-libffi of 'Unknown type name' when Archiving, but Build fine.
I tried to re-installed the BlocksKit but cannot use it anymore.

In the Podfile:
platform :ios , '6.0'
pod 'BlocksKit'

Any idea?

Just checked the source and added "bk_" prefix to all the methods.
Worked again!
