Comment:

 It built fine on our automated build system, so something must be
 different about your system.

 Looking at your log and comparing it to mine, I note some differences. I
 see your tarball was extracted using /bin/tar. This is unexpected, because
 no such program exists on a stock macOS system. (On macOS, it's installed
 at /usr/bin/tar.) So what is /bin/tar and how did it get there, and what
 else has been installed into system directories that shouldn't be there?

 As you noted, your build decided to use the library nsl; it also decided
 to use the library crypt. My build doesn't try to use either library.
 Neither library is part of macOS nor MacPorts. I'm not certain why your
 build did this, and it doesn't look like perl's Configure script creates a
 log so we can't inspect that either. But I added `set -x` near the
 beginning of the Configure script to see the commands it was running, and
 it looks like among other places it looks in /usr/local/lib for libraries.
 Do you perhaps have libcrypt and libnsl installed there? If so, please
 remove them (see wiki:FAQ#usrlocal). The Configure script also looks in
 /usr/lib, and although these libraries are not part of macOS and should
 not be there, we already know you have at least one file installed in a
 system directory that should not be there, so maybe there are others, so
 check /usr/lib for these libraries too. If you can find these libraries
 and remove them, clean perl5.28 and try again.
