Just a comment here : we have been installing and using mod_perl2 for many years on many 
servers with Linux Debian, and installing it using the normal Debian package manager 
commands, without any problems that I can recall.

e.g.

root@kunz:~# uname -a
Linux kunz 4.9.0-11-amd64 #1 SMP Debian 4.9.189-3+deb9u2 (2019-11-11) x86_64 GNU/Linux

root@kunz:~# apt-cache search mod_perl
[ .. long list, among which ..]

libapache2-mod-perl2 - Integration of perl with the Apache2 web server
libapache2-mod-perl2-dev - Integration of perl with the Apache2 web server - development files
libapache2-mod-perl2-doc - Integration of perl with the Apache2 web server - documentation

root@kunz:~# apt-get install libapache2-mod-perl2

libapache2-mod-perl2 is already the newest version (2.0.10-2+deb9u1).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
root@kunz:~#

So I guess that your issue above does indeed have to do with the specific SUSE packages, 
and you should probably discuss that with them.
