The following document suggests that LLDB should be buildable on
Leopard (which is what I'm experimenting with first):
After following those instructions, and attempting to build lldb
r106806 from within Xcode 3.1.4 (the latest version for Leopard,
correct?) I get over 500 build errors.
Build transcript attached.

lldb doesn't support building on Leopard (Mac OS X 10.5). It could be made to work if someone wanted to spend the time on it but it's not something any of us at Apple are going to do. The code signing hasn't changed since Leopard; these instructions were originally used for our internal code signing of gdb binaries back in the Leopard timeframe, I think Jim did little more than s/gdb/lldb/ on those instructions and added them to the repository.
