The llvm-top stuff is designed to handle all the dependencies for you.
In fact, all you needed to do was issue "./install llvm-gcc-4.0" and it
would have checked out llvm for you, built and installed it and then
built and installed llvm-gcc-4.0. At least, that's the way it is
supposed to work.

No, its not expected. I'm trying to replicate here because I thought
this was working. There are two problems you reported:

1. llvm-gcc-4.0 should have been checked out into the llvm-top
directory.
2. The install of llvm-gcc-4.0 should have worked.

Thanks for noting it. I'll take a look and see if there's a bug.

FYI: llvm-top isn't ready for prime time yet (hasn't even been
announced) as it needs more testing. Thanks for testing! :)
