Hello, It looks like the mkbundle NAnt task is failing with the mono 2.8 builds for os x. apparently this is because the mono.pc file now does not define any library or include paths. these paths are instead defined in the mono-2.pc pkgconfig file.
I had to make a simple change to the file src/tools/NAnt.MonobjcTasks/Tasks/MakeBundleTask.Generation.cs to get it to call pkgconfig with "mono-2" as the argument. --Anthony
