The ListSourceFilesInTarget script munges through the Xcode project looking for references to resources that it should copy into the static frameworks. But, it seems to have run across an object of some type in the Xcode project that it hasn't been set up to handle, a "XCVersionGroup".

Is this using a Xcode 4 preview? If not, any hints on how you structured your project to get this type of object in the project file would help narrow it down.

For now, you might be able to hack in support for (or at least ignore) this type in the script where this call is made (about line 138).
