rust build fail

The rust build inside the fedora oci image is currently failing
reproduce with: $ make oci-fed-image

I'm unable to reproduce this issue in my system. Below is the output (last few lines) of make oci-fed-image

Hi @manojgop

The rust build is failing for the git workflow - which will block PRs being merged. Going to hijack this issue for this

The steps to reproduce:

setup an ubuntu docker container using the ubuntu:latest images

Follow the instructions to build cndp and the rust examples... the following error occurs:

Also fails on fedora:latest but with a different error

It's also failing in our github workflow: https://github.com/CloudNativeDataPlane/cndp/actions/runs/6853611616/job/18634770398 <<<<< fixing this would be the priority
