Dear GMP maintainers,
this thread seems to died. Is there anything I could to do to help
along with the decision?
Just to sum it up:
* GMP currently is LGPLv3+
* GnuTLS 3.x is using GMP (via nettle)
* There is some quite important software which uses GnuTLS is licensed
GPLv2 (without the "or later" clause). The most important example is
cups. This is blocking e.g. Ubuntu  or Debian  to upgrade GnuTLS to
its latest feature release.
* GNU's suggested solution for this problem seems to be to dual license as
Thanks for considering this.
 Quoting changelog:
gnutls26 (2.12.14-5ubuntu1) precise; urgency=low
* Start building gnutls-bin from this source package again, superseding
the version in gnutls28: gnutls28's licensing is currently too strict
for many of the free software packages built against it in Ubuntu main
and we only want to support a single version. Bump its version to
`What a good friend you are to him, Dr. Maturin. His other friends are
so grateful to you.'
`I sew his ears on from time to time, sure'
