Can I remove one LLVM ?
I have llvm 18 and 19.
I have been using stable Gentoo.

Code:
alculating dependencies... done!

Try it and see. What is the output of emerge --ask --verbose --depclean sys-devel/llvm?

No. Mesa specifically needs 18, at least for now:

If emerge --depclean does not want to clean it, something holds on to it. GDH-Gentoo has already given you the answer to what it is.

You don't need to remove it, it won't do much for you. It won't even free significant amount of space and it doesn't run by itself, so you don't have a good reason to want to remove it until emerge --depclean decides so.

Best Regards,
Georgi
