Hi, we have a custom perl 5.8.9 and want to run on RHEL 8.x but as of v8 libnsl needs to be installed separately. Not an issue for us but some clients have difficulty changing their systems with yum install or what-not. So on our CentOS7 build system, renamed libnsl.so* so they wouldn't be found. The Configure script for perl leaves libnsl out since it's not found, but at the end of the make I see, 
LD_LIBRARY_PATH=/home/lint/build/perl/perl-5.8.9 /home/lint/build/perl
+/perl-5.8.9/preload /home/lint/build/perl/perl-5.8.9/libperl.so gcc -

I can't figure out where the shared library request for libnsl.so.1 is coming from! Any suggestions? For instance, would I be better off trying to rebuild perl on a RHEL 8.x system instead? Or perhaps libnsl really is necessary for perl up to and through version x.xx? Thanks!
