STRONGLY recommended reading:

  * The pkgsrc Guide, see pkgsrc/doc/pkgsrc.{txt,html}, AKA
    http://www.netbsd.org/Documentation/pkgsrc/
    which contains a lot of details you need to at least have a basic idea
    about (and which you apparently don't have, sorry)

  * Easy Software Installation on Linux, Solaris, NetBSD etc. using pkgsrc,
    a brief introduction to pkgsrc including its dependency system, see
    http://www.feyrer.de/Texts/Own/21c3-pkgsrc-paper.pdf
