Note:
As the 'tools/Changelog' shows, gpg-zip is not installed with gnupg2 because
it gets installed by gnupg. Strangely gnupg2 still tries to install a gpg-zip
manpage which ofcourse conflicts too.

* Makefile.am (gpg-zip, gpgsplit): Do not install due to a
conflict with gpg1.

CVE-2008-1530 (High) :
GnuPG (gpg) 1.4.8 and 2.0.8 allows remote attackers to cause a denial of service (crash) and
possibly execute arbitrary code via crafted duplicate keys that are imported from key servers,
which triggers "memory corruption around deduplication of user IDs."
