$
/Users/ribrdb/Documents/git/lldb/DerivedData/lldb/Build/Products/Debug/lldb
dyld: Library not loaded: @rpath/LLDB.framework/LLDB
  Referenced from:
/Users/ribrdb/Documents/git/lldb/DerivedData/lldb/Build/Products/Debug/lldb
  Reason: image not found
Trace/BPT trap: 5
$ otool -lv
/Users/ribrdb/Documents/git/lldb/DerivedData/lldb/Build/Products/Debug/lldb|grep
-A2 LC_RPATH
          cmd LC_RPATH
      cmdsize 32
         path @loader_path (offset 12)
$ file
