error when building llvm from svn

I have been building llvm from svn via a script for sometime now. But lately I have encountered the following
error when building:

cat /Volumes/lacie_disk/src/llvm/tools/llvm-config/FinalLibDeps.txt >> /Volumes/lacie_disk/src/llvm/Release/bin/llvm-config
cat: /Volumes/lacie_disk/src/llvm/tools/llvm-config/FinalLibDeps.txt: No such file or directory
make[1]: *** [/Volumes/lacie_disk/src/llvm/Release/bin/llvm-config] Error 1
make[1]: Leaving directory `/Volumes/lacie_disk/src/llvm/tools/llvm-config'
make: *** [all] Error 1

My platform is OS X Leopard on an Intel machine.
I am compiling an optimized released build.
