Cannot install sippy_cup on CentOS 8 (minimal install)

[Palezvar]

I tried to compile sippy_cup from source code but getting the following error when I try to start a test scenario that I copied from the github web site:

[root@sip-centos1 ~]# /root/sippy_cup/bin/sippy_cup -r test.yml
Traceback (most recent call last):

Before cloning the repo and running "bundle install", I executed the following to prep the environment:

dnf -y install dnf-plugins-core
dnf upgrade
dnf -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
dnf config-manager --set-enabled powertools
dnf -y group install "Development Tools"
dnf -y install make cmake gcc-c++ ncurses-devel openssl-devel flex bison libpcap libpcap-devel lksctp-tools-devel git
dnf module install ruby:2.7
dnf install ruby-devel

Am I missing a dependency? I am using sipp 3.7.

Thanks
