llvm dev - Nov 2011 - [LLVMdev] [make] fatal error: 'LibraryDependencies.inc' file not found

I'm trying to build llvm from svn.

I ran ./configure with --enable-debug-runtime, then make -j4, before I
got the following error:

llvm[1]: Building llvm-config script.
make[1]: Leaving directory `/home/vk/opt/llvm/tools/llvm-config'
make[1]: Entering directory `/home/vk/opt/llvm/tools/llvm-config-2'

It looks like some other poor soul has had this issue:

How do I go about fixing this issue?

best,

* I've heard there have been some changes to llvm's build system
recently. I looked through a few month's worth of archives to see if
anyone else has had this problem, but I may have missed something.

llvm's build system assumes that PYTHON_EXECUTABLE points to a 2.x
interpreter. On Arch Linux, at least, it points to a 3.x interpreter.

I modified CMakeLists.txt to use "python2" if a 3.x interpreter is
detected.

If "python" points to a 3.x interpreter and "python2"
doesn't exist,
this workaround will break loudly.
