I've done some steps to diagnose the case. Seems that /usr/bin/tar
does not create correct library:
-----
% file 
/usr/ports/devel/nspr/work/nspr-4.9/mozilla/nsprpub/build/dist/lib/../../pr/src/./libnspr4.so.1
/usr/ports/devel/nspr/work/nspr-4.9/mozilla/nsprpub/build/dist/lib/../../pr/src/./libnspr4.so.1: 
ELF 32-bit LSB shared object, Intel 80386, version 1 (FreeBSD), 
dynamically linked, not stripped
% file /usr/local/lib/libnspr4.so.1
/usr/local/lib/libnspr4.so.1: data
% hd -C /usr/local/lib/libnspr4.so.1
00000000  00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00

% tar --version
bsdtar 3.0.3 - libarchive 3.0.3
-----

The library (/usr/local/lib/libnspr4.so.1) is created by the command:
-----
/usr/bin/tar -C 
/usr/ports/devel/nspr/work/nspr-4.9/mozilla/nsprpub/build/dist/lib 
--dereference -cf - . |  /usr/bin/tar -C /usr/local/lib -xof -
