>Description:
 When using pkg_info -qg <package>, one can obtain a list of files which fail the MD5 checksum. A list of files of the form "<file> fails the original MD5 checksum\n" will be output to stdout. If a file is missing, however, it is *not* listed as failing the checksum. Instead, the following message is printed to stderr: "pkg_info: <file> doesn't exist\n\n".

While the semantics of "failing an MD5 checksum" may be up for debate (does a missing file fail because it is missing?) it seems that the intent of the -g option is to do an integrity check on the package. Missing files are clearly an integrity problem, but parsing the stdout of pkg_info -g will not include them.
>How-To-Repeat:
Choose a file from an installed package. Move the file to a backup area. Run pkg_info -qg <package>.
>Fix:
      My suggestion, therefore, is to do away with the stderr message in the case of a missing file, and instead output a message to stdout of the form "<file> does not exist".

The change is actually a one liner. Change /usr/src/usr.sbin/pkg_install/info/show.c:283 from
warnx("%s doesn't exist\n", tmp);
to
printf("%s does not exist\n", tmp);

As an aside, even if this change is not accepted, the '\n' in the warnx is redundant and should be removed.
