<http://www.idefense.com/application/poi/display?id=152&type=vulnerabilities>

* pkgsrc changes:

  - Don't use PKGNAME within DIST_SUBDIR.  Instead, date based DIST_STAMP.
    This change prevent extra DIST_SUBDIR change asked by kim@.

    dnsserver itself is problematic with huge size of squid process.
