Thank you! Is that documented somewhere? (I tried reading
https://www.netbsd.org/support/query-pr.html and at the page for my PR.)

It is happening to me even with the default /usr/pkg.

I just tried again with these steps:

1. Make a new clone of the pkgsrc git mirror at commit ac347f1c (Dec 9).

2. pkg_delete -f perl (to remove the binary package I had installed)

3. In the lang/perl5 directory, "make install" and give my root password
when needed. (I skipped bootstrapping since I'm on NetBSD and I want it
under /usr/pkg; hope that's ok.)

And then for example Cwd.so doesn't have the full RPATH, even though the perl binary does:

ucl falsifian $ readelf -d /usr/pkg/lib/perl5/5.42.0/x86_64-netbsd-thread-multi/auto/Cwd/Cwd.so|grep -i rpath 
  0x000000000000000f (RPATH)              Library rpath: [/usr/pkg/lib]
ucl falsifian $ readelf -d /usr/pkg/bin/perl|grep -i rpath                                                    
 0x000000000000000f (RPATH)              Library rpath: [/usr/pkg/lib:/usr/pkg/lib/perl5/5.42.0/x86_64-netbsd-thread-multi/CORE]

Compared to what I see after using pkgin to get back the binary package
(from a quarterly branch):

ucl falsifian $ readelf -d /usr/pkg/lib/perl5/5.42.0/x86_64-netbsd-thread-multi/auto/Cwd/Cwd.so|grep -i rpath 
 0x000000000000000f (RPATH)              Library rpath: [/usr/pkg/lib:/usr/pkg/lib/perl5/5.42.0/x86_64-netbsd-thread-multi/CORE]
ucl falsifian $ readelf -d /usr/pkg/bin/perl|grep -i rpath                                                    
 0x000000000000000f (RPATH)              Library rpath: [/usr/pkg/lib:/usr/pkg/lib/perl5/5.42.0/x86_64-netbsd-thread-multi/CORE]

I'm afraid I know almost nothing about how pkgsrc handles RPATHs.
