I have two different machines with LLVM source trees on them.
One builds fine, the other gives the error above.
This behavior started on Tuesday.
Both machines have the sources on a non-boot disk.
The source trees are identical, and in both cases, I have a separate object directory.
I have removed the object directories, and reran configure:
Still get the same behavior (success on one, failure on the other).

The only differences that I can think of are:
1) The unsuccessful machine has recently had XCode 4 installed.
2) The successful machine has the sources on a volume with a case-sensitive file system.
