Hi Paul,
Swarm will not work with gcc-4.7.0. More specifically, gcc-4.7.0 has the new
GNU Objective-C runtime library which has been extensively changed to be
compatible with Objective-C v2.0 from Apple.
My guess is that Swarm seemed to build because it was looking at the ObjC
header files within Swarm itself, while Heatbugs is looking at the system
header files (/usr/include/objc) and thus the conflict.
