Sciunit doesn't work when the reproducer has a much older versions of glibc

[charmoniumQ]

I tried creating two podman containers with podman run -it --rm ubuntu:23.04 and another with ubuntu:20.04.

Then I ran the following:

apt update
apt install -y python3 python3-pip python3-venv cmake git
python3 -m venv venv
source venv/bin/activate
pip3 install git+https://github.com/depaul-dice/sciunit

In the 23.04 container, I ran:

sciunit create test
sciunit exec pwd
sciunit copy

So far, so good. In the 20.04 container, I ran:

sciunit open $key_from_previous_container
sciunit repeat e1

The last command fails with, outputing only:

../cde-exec: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.33' not found (required by ../cde-exec)
../cde-exec: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by ../cde-exec)
b''

This works fine if the containers have the same Ubuntu versions, but fails when their glibc is different (as far as I can tell) ldd --version | head --lines=1.

I think this is because cde-exec depends on glibc, the compiled version of cde-exec (compiled for a specific glibc) makes its way into the sciunit package, but glibc does not, so when another client tries to run the sciunit package, their invocation of cde-exec can't find the right version of glibc.

Note, I am using Podman 5.1.1.
