LLDB build instructions for MacOSX: broken link, outdated web information

Dear All,

since a couple of days I try to build LLDB on Mac OSX Snow Leopard,
following http://lldb.llvm.org/build.html

The page has the following problems:

- link "LLDB Mac OS X x86_64 build with Clang (XCode)"
   http://lab.llvm.org:8011/builders/lldb-x86_64-darwin11

   results in 404 - not found

- link "Download the lldb sources" in the MacOSX section points to
   http://lldb.llvm.org/download.html

   which only has Debian & Co. (binary) packages

Best regards

    Björn
