Update to 1.4.6:

Noteworthy changes in version 1.4.6 (2006-12-06)
------------------------------------------------

    * Fixed a serious and exploitable bug in processing encrypted
      packages. [CVE-2006-6235].

    * Fixed a buffer overflow in gpg. [bug#728, CVE-2006-6169]
	(already fixed in pkgsrc)

    * Fixed a bug while decrypting certain compressed and encrypted
      messages. [bug#537]

    * Added --s2k-count to set the number of times passphrase mangling
      is repeated.  The default is 65536 times.

    * Added --passphrase-repeat to set the number of times GPG will
      prompt for a new passphrase to be repeated.  This is useful to
      help memorize a new passphrase.  The default is 1 repetition.

    * Added a GPL license exception to the keyserver helper programs
      gpgkeys_ldap, gpgkeys_curl, and gpgkeys_hkp, to clarify any
      potential questions about the ability to distribute binaries
      that link to the OpenSSL library.  GnuPG does not link directly
      to OpenSSL, but libcurl (used for HKP, HTTP, and FTP) and
      OpenLDAP (used for LDAP) may.  Note that this license exception
      is considered a bug fix and is intended to forgive any
      violations pertaining to this issue, including those that may
      have occurred in the past.

    * Man pages are now build from the same source as those of GnuPG-2.
