And now it is. Try this patch.

The problem with the shell script is that, when run on Darwin, it assumes it was run from Xcode. Not all of us use Xcode to build on Darwin ;). Personally, I would like to get rid of the duplication of effort between the shell scripts and the makefiles, but I haven't figured out how I want to do that yet.

Imagine that you're debugging a program on a remote Mac OS X system.
