as showned above ir succeeded to build 2 months ago.
Can't remember if I had to fiddle to have it works.

This issue now pops up whatever media-gfx/blender slot is requested...

Any clue how to fix keeping USE=osl?

Thks 4 ur attention, interest & support.

Kinda back to LFS mode in gentoo:
Temporary
Code:
quickpkg --include-config y llvm:16 llvm:17 llvm:18
emerge -C llvm:16 llvm:17 llvm:18
echo Now only llvm:15 installed, the one in use for stable media-libs/osl-1.12.7.0
emerge blender
emerge -1 -K llvm:16 llvm:17 llvm:18


Plz post how to avoid such a mess, if possible? (GLOBAL VARIABLE, ebuild patching ...)
