With ~amd64 and unmasked nvk flag, building the mesa package fails trying to resolve libunwind when linking NVK related .so file. Installing sys-libs/libunwind fixes the problem.
Could you attach the log of it failing so we can see the issue please.

I looked and didn't see any obvious usage of libunwind in nvk. Maybe it's from one of the rust dependencies?

Using `qlist -e media-libs/mesa:0 | xargs scanelf -BF '%n'` I notice that libunwind.so.1 library are needed for /usr/lib64/libvulkan_nouveau.so Sorry I didn't run the command when doing my tests and complete forget that `sys-libs/llvm-libunwind` is included on the LLVM profile. To fix it you might just need to add this to nvk RDEPENDS: || ( sys-libs/llvm-libunwind sys-libs/libunwind ) It very strange why the src/nouveau/vulkan/meson.build doesn't include dep_libunwind as part of the nvk dependencies: https://gitlab.freedesktop.org/mesa/mesa/-/blob/main/src/nouveau/vulkan/meson.build?ref_type=heads#L74
I tried to reproduce the issue locally and I could not. Could this somehow be related to musl, which I see you are using? Gonçalo: were you able to reproduce the issue? Were you able to see some shared objects installed by mesa linked with libunwind even with USE=-unwind?

I don't have USE=-unwind enable, so It confirm that at least in the llvm profile and musl sys-libs/libunwind is required
