zstd not being recognized by ./glibc_run.sh

[austinzwile]

When attempting to run tools under a certain glibc version with ./glibc_run.sh I am getting an error saying zstd is not found. This is after running:

Check you have installed zstd

This was done inside the docker. Any thoughts on how to remediate? Thank you in advance.
