 I believe I found the problematic script and tried the following patch:
 richard@devzone:~/src/pkgsrc/mk/pkgformat/pkg$ pkgdiff metadata.mk
 $NetBSD$

 this allows building the package without the pkg_info error (also worked 
 for nspr)
 
 What I don't like is the gnu-ism...from the xargs man page:
       --no-run-if-empty, -r
            If the standard input does not contain  any  nonblanks,
            do  not  run the command.  Normally, the command is run
            once even if there is no input.  This option is  a  GNU
            extension.
 
 I believe there should be a better way to do this, but I'm afraid it is 
 perhaps better for the pkgsrc maintainers to determine the best approach.
