[LLVMdev] xcodebuild and LLVM

[John Criswell]

Dear Ted and All,

Thanks.  This has helped some.  However, I'm now getting errors from 
libtool about an object being modified after free.

Is libtool supposed to work with LLVM bitcode files?  If so, would 
grabbing the latest source potentially fix the problem (I'm currently 
using XCode 3.1), or will I need a way to convince xcodebuild to use 
something other than libtool?
