I can confirm this happens on my box, too. It is triggered by wasm USE-flag. The fix is to change one forgotten path in the ebuild: diff --git a/dev-lang/rust/rust-1.48.0.ebuild b/dev-lang/rust/rust-1.48.0.ebuild index 16a3d1da232..d89b0fa8404 100644 --- a/dev-lang/rust/rust-1.48.0.ebuild +++ b/dev-lang/rust/rust-1.48.0.ebuild @@ -213,7 +213,7 @@ src_configure() { if use system-llvm; then # un-hardcode rust-lld linker for this target # https://bugs.gentoo.org/715348 - sed -i '/linker:/ s/rust-lld/wasm-ld/' src/librustc_target/spec/wasm32_base.rs || die + sed -i '/linker:/ s/rust-lld/wasm-ld/' compiler/rustc_target/src/spec/wasm32_base.rs || die fi fi rust_targets="${rust_targets#,}" With this, src_configure passes for me.

thanks for catching, I will replace this sed with a patch bit later.
