Please find attached cvc-2.1.3.tar.gz which provides an ebuild for the Nortel Networks Contivity Extranet Client provided by Netlock. I suggest this should be imported into net-misc/cvc. This ebuild can not fetch the tarfile because the website requires registration and a purchase before you can access it. Also, find attached cvc-2.1.3-license which is the license associated with this package, that I refer to as "CVC" in the ebuild.

Please, attach a plaintext ebuild and reopen then, if you still want this in portage. http://www.gentoo.org/proj/en/devrel/handbook/handbook.xml?part=2&chap=3#doc_chap2
