Definitely not. It looks like your setup is a bit screwed - if it really is 12.04, there should not be any "quantal" packages on it (quantal = 12.11) Might be because of Cinnanmon, if you installed 1.6 targeting Mint's Nadia release (but there's a backport to 12.04 based Maya, which should not pull any quantal packages into the system, at least it did not for me).
Also, which DEB did you use? The one directly from opencpn
.org or from the Launchpad PPA?
Anyway, this looks like a situation very specific for your machine and hardly resolvable during packaging.
