I still haven't received any comment on this. Isn't anyone interested?

Since DFSG apparently (according to the recent discussion) only deals with 
copyright and restrictions imposed by the copyright owner, I assume that 
uploading the independently developed Perl packages, libmail-domainkeys-perl 
and libmail-dkim-perl, should be possible. Just one more question: 

What about the Perl license and the OpenSSL license (my packages depend on 
Perl OpenSSL wrapper packages)? The Perl license is a dual license 
("Artistic", which goes fine with OpenSSL (right?), + GPL, which is 
incompatible with OpenSSL. Doesn't the OpenSSL dependency destroy the GPL 
license option? Perhaps not for my packages, but for libcrypt-openssl-*-perl?

Can someone please explain the full implications? My head is spinning...
