App fails to build with SDK 3.5.0 and 3.5.1

Hi

I get the following build error when building my app with the Titanium SDK 3.5.0 and 3.5.1

2015-04-10 09:08:15.767 xcodebuild[14428:5903]  DeveloperPortal: Using pre-existing current store at URL (file:///Users/XXXX/Library/Developer/Xcode/DeveloperPortal%206.2.db).
** BUILD FAILED **
The following build commands failed:
    Ld build/SocketTest2.build/Debug-iphonesimulator/SocketTest2-universal.build/Objects-normal/x86_64/SocketTest2 normal x86_64
(1 failure)

It must be something to do with a module I have in the project... Because if I remove the module it builds fine... I created the module myself... is there something I could be missing in the module? Any ideas please let me know
