This is a common misunderstanding, you don't have to license something
under *gpl just because you are _using_ something *gpl on it. You can
create privative software using gpl libraries and utilities as long as
you distribute them under the same license.

What you can't do is modify something under *gpl and distribute it
under a privative license

Again, not using, but distributing a modified version
