Arch Linux

It compiles and works but could you add the desktop file and other things that are not installed with the PKGBUILD?

I hope this is better. The last commit is the same as the latest tagged release 2.1.36 atm anyway.

Not really, it's actually just for the sake of having the bleeding edge version of the program. Sometimes it's useful, when the sources are already updated to fix problems that are still on the current official release. Some prefer to build it from the latest source code instead of the official release (latest official pre-bundled source code archive).

The pre-bundled archive may be used as a source for the 'non-git' version of this package, however. I assume the link in Last.fm website is outdated.

This can stay here, you just need to format your PKGBUILD properly for Git.

Ah, I see now that I shouldn't call it -git unless it's a non-released git commit. But what to do in a case like this? When the version on the official website is outdated and there is a later release on github?

I could do that. But like I said on the other package's entry already. This is using the lastfm sources from github: https://github.com/lastfm/lastfm-desktop
That's why it has a higher version number. The 'original' lastfm package pulls the sources from the official website, not from github.

You are supposed to make pull request from the git repo through the PKBGUILD. See these for more info:
