Demonstrates bug with no BUILD in dir with BUILD.gen

What I expected:

./pants goal bundle src/java/com/pants/examples/pingpong

to work if there is a file named BUILD.gen but no corresponding BUILD file


What I got:

./pants goal bundle src/java/com/pants/examples/pingpong
The following targets could not be loaded:
  src/java/com/pants/examples/pingpong =>
    IOError: BUILD file does not exist at: /Users/zundel/Src/Pants/src/java/com/pants/examples/pingpong/BUILD
