Unable to compile SNIProxy on RHEL 7.7

Hey there, I've been hacking away at this issue for a few days now and I'm running out of ideas. I was hoping one of you kind folk could give me a hand.

I've been running SNIProxy as part of a Lancache config on Ubuntu for some time now and it's been working great. However, I need to migrate the services to a hosted server in my company, and the only supported OS is Red Hat 7. I've managed to get everything else working, but this app just will not cooperate for me.

When I try to compile the code I'm getting some errors from autogen.sh. Here's the output from the command:

server:/temp/sniproxy[ 60 ] --> sudo ./autogen.sh
./setver.sh: line 35: debchange: command not found
configure.ac:20: error: possibly undefined macro: AC_LIB_HAVE_LINKFLAGS
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
configure.ac:22: error: possibly undefined macro: AC_SUBST
configure.ac:24: error: possibly undefined macro: AC_MSG_ERROR
configure.ac:47: error: possibly undefined macro: AS_IF
autoreconf: /usr/bin/autoconf failed with exit status: 1

Looking online, I've only found people who were missing certain packages encountered this sort of "undefined macro" issue. Assuming the prerequisite list is complete, I believe this should not be the cause for my issue. Here's the output from the YUM command provided in the readme:

server:/temp/sniproxy[ 59 ] --> sudo yum install autoconf automake curl gettext-devel libev-devel pcre-devel perl pkgconfig rpm-build udns-devel

Nothing to do

On the off chance that I could ignore those errors, I went ahead to the next command, and am greeted with more errors (which isn't surprising). Running the configure script gives me the following:

I've tried modifying scripts, installing alternate packages, and tweaking things to get around these errors, but nothing seems to help. The very last thing I tried was compiling the code on Ubuntu and then packaging it as an RPM to install on the RHEL server. While this did allow me to install the application, it seems like something is incompatible with this method as trying to browse to a location that is functional with my Ubuntu server at the helm, gives me an error stating:

Cannot connect securely to this page This might be because the site uses outdated or unsafe TLS security settings. If this keeps happening, try contacting the website's owner.

Unfortunately, I do not have enough knowledge of this build process, or how the application truly functions to be able to troubleshoot this issue any further. If anyone could help me with this issue, I'd be extremely thankful!
