 ### Build from Source
 The rust-agent needs to be built statically and linked with `musl`

+> **Note:** skip this step for ppc64le, the build scripts explicitly uses glibc for ppc64le.

 ```bash
 $ arch=$(uname -m)
-$ [ "$arch" == "ppc64le" ] && arch=powerpc64le
 $ rustup target add "${arch}-unknown-linux-musl"
 $ sudo ln -s /usr/bin/g++ /bin/musl-g++
 ```
