The clients are no longer part of this port, but will be built by
the argus-clients port, which is listed as a dependency.
Since both the argus and argus-clients ports contain the same
COPYING file and want to install it into the same directory, I have
disabled installation of the copyright file by this port, assuming
that the dependent argus-clients port already did it ...
not based on the patch offered (I already had prepared diffs more than
one week ago, but had no time to perform the commit). I choose to use
my patches instead of those from the PR, since they seemed even more
correct ;-)
