jlam b032c82c21 If the package directory doesn't exist, then return a non-zero code. This

# NAME
# pkg_path -- canonicalize directories into "package paths"
#
# SYNOPSIS
# pkg_path [-s pkgsrcdir] dir ...
#
# OPTIONS
# The following command line arguments are supported.
#
# -s pkgsrcdir Use the specified directory as the path to the
# pkgsrc directory tree. By default, this is the
# value stored in the PKGSRCDIR environment variable.
#
# DESCRIPTION
# pkg_path canonicalizes the specified directories into package
# paths are are relative to the pkgsrc directory tree, and prints
# each of them to standard output on a new line. The specified
# directories are taken to be relative to the current directory or
# are otherwise absolute paths. Directories that are not valid
# package directories or are not found are skipped during processing.
#
# ENVIRONMENT
# PKGSRCDIR This is the location of the pkgsrc directory tree,
# which defaults to "/usr/pkgsrc".
