If you are using Mac OS X, please read "README.MacOSX" as well.

Terse instructions:

$ ./ufsdiskimage create ~/Documents/NetBSD 512  # megabytes - season to taste
$ ./ufsdiskimage mount ~/Documents/NetBSD
$ sudo chown `id -u`:`id -g` /Volumes/NetBSD
$ curl -O \
    ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-current/tar_files/pkgsrc.tar.gz
$ tar -C /Volumes/NetBSD -zxvf pkgsrc.tar.gz && rm pkgsrc.tar.gz
$ sudo ./bootstrap \
    --prefix=/Volumes/NetBSD/pkg \
    --pkgdbdir=/Volumes/NetBSD/pkgdb

Note: if you already have a UFS partition, or have a spare partition
that you can format as UFS, use that instead of the UFS disk image.
It'll be somewhat faster and will mount automatically at boot time.

(Why can't you just use the HFS+ filesystem you've already got?
Because pkgsrc currently requires the underlying filesystem to be
case-sensitive, and HFS+ isn't.)
