Munge make check fails on fresh Ubuntu

Dear all,

I'm a novice at HPC job scheduler installation (but a frequent user) and I'm running into a fair number of roadblocks trying to get SLURM up and running. One of those roadblocks is getting Munge installed and/or recognised during the slurm ./configure.

Some information concerning the small login node for my cluster:

NAME="Ubuntu"
VERSION="20.04.2 LTS (Focal Fossa)"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 20.04.2 LTS"
VERSION_ID="20.04"
HOME_URL="https://www.ubuntu.com/"
SUPPORT_URL="https://help.ubuntu.com/"
BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/"
PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy"
VERSION_CODENAME=focal
UBUNTU_CODENAME=focal
5.4.0-1041-raspi

Firstly, I've tried sudo apt-get install munge. This works fine but SLURM can't find the Munge installation directory. In fact, I don't know where it is myself, so any help with that would be great.

Secondly, I've tried installing Munge following the instruction on github. To be fair, I'm really unsure about what I'm doing!
I made a directory:

/home/mpiuser/munge

Then I made subdirectories and adjusted the permissions according to the instructions given:
drwx------ 2 mpiuser mpiuser 4096 Aug 4 19:05 etc
drwxr-xr-x 2 mpiuser mpiuser 4096 Aug 4 19:05 run
drwx------ 2 mpiuser mpiuser 4096 Aug 4 19:05 var

Then I tried the ./configure:

./configure --prefix=/usr --sysconfdir=/home/mpiuser/munge/etc --localstatedir=/home/mpiuser/munge/var --runstatedir=/home/mpiuser/munge/run --with-crypto-lib=openssl

Followed then by make and finally makecheck. That's then when I ran into lots of errors and fails:
============================================================================

This is just the very start of the t/test-suite.log file:

I suspect many of these errors are going to be caused by the same fault. Suggestions are warmly welcomed.

Thanks
