Describe the bug

lldb from llvmPackages_14.lldb seems to be broken, reporting:

$ lldb --version
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'lldb'
lldb version 14.0.0

This error is present in all invocations of lldb I've tried: with no arguments, pointed at an executable, and debugging a coredump (SYSTEMD_DEBUGGER=lldb for coredumpctl debug(/gdb), FWIW).

Coredump usage is worse, with something like:

$ coredump debug
...<<snip>>...
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'lldb'
(lldb) target create "<<redacted>>" --core "/var/tmp/coredump-VXmhXt"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
NameError: name 'run_one_line' is not defined
Traceback (most recent call last):
  File "<string>", line 1, in <module>
NameError: name 'run_one_line' is not defined
Traceback (most recent call last):
  File "<string>", line 1, in <module>
NameError: name 'run_one_line' is not defined
Traceback (most recent call last):
  File "<string>", line 1, in <module>
NameError: name 'run_one_line' is not defined
Traceback (most recent call last):
  File "<string>", line 1, in <module>
NameError: name 'run_one_line' is not defined

Core file '/var/tmp/coredump-VXmhXt' (x86_64) was loaded.

Steps To Reproduce

Steps to reproduce the behavior:

1. lldb --version or other lldb invocations, until this is fixed this works: nix run nixpkgs#llvmPackages_14.lldb -- --version.
2. Note the messages as described above

Expected behavior

LLDB doesn't show this error, and presumably whatever functionality triggering this isn't working properly but I haven't tried using it after the error(s) are printed.

Additional context

Another LLVM14 package to fix before this is ready for use:
