Version 5.0.0 of python-pylast requires two new runtime dependencies:
* python-importlib-metadata
* python-httpx

For example, without python-httpx, this error is produced by an application that depends on python-pylast:
from pylast import WSError, Tag
File "/usr/lib/python3.10/site-packages/pylast/", line 37, in <module>
import httpx
ModuleNotFoundError: No module named 'httpx'
(Note: this is a partial stack trace)

Any use of this library is impossible without these dependencies.

Additional info:
You can see these dependencies declared here:

Additionally, from what I can tell, it does not appear that this lib requires python-six as a runtime dependency. There are no references to python-six in the lib's sourcecode. I believe you should be able to remove this as a required runtime dependency.

Steps to reproduce:
As an example, try installing foobnix from the AUR, which depends on python-pylast. Ensure you do not have one or both of those dependencies installed (I haven't tested python-pylast without python-importlib-metadata installed, as other software I have installed depends on that library). It will fail to start with the above stack trace until you install python-httpx and python-importlib-metadata.

I have the same issue with missing python-httpx. The addition of this dependency can be seen in the upstream changelog here:

I've had the same issue today after upgrading an app,
