As author you can take legal actions against anyone who voilates
your licensing terms. This is hard to do for military organisations
because they usually do have a special legal situation.

If you did that as a recommendation would that be enough?

This is not true as I do have a tarball for 1.2, which we used for
the FreeGIS CD rpms, which only has the GPL license included.

I wish it would be as simple as this, participating in several
discussions on gnu.misc.discuss I know that it is complicated.

iGMT is not useful without GMT and therefore creates a combined
product with it, I think that US legal interpretations consider the
combination as a product a derived work.
