Hi Gubbins developers,

I'm writing you on behalf of the Debian Med team that has the objective
to package all software that might be relevant in the fields of medicine
and biology.  We have received a request to package Gubbins from a user
and thus we have put it on our todo list[1].

I noticed that Andrew Page has dropped some packaging stuff into the
download tarball.  Since I intended to keep the history I kept his
changelog entries and added Andrew to the Uploader field in
debian/control.  Feel free to checkout the current packaging from
the official Debian development platform[2].  Andrew, you are more
than welcome to join the Debian Med team and take part in the effort
to make Gubbins an official Debian package.

When trying to create the package I stumbled upon some issues I would
like to discuss.  At first I'm a bit concerned about the usage of
fastml2.  The problem is that this is not Free Software and according
to the license that says:

 This repository provides some additional functionality to fastml to allow it to
 work with Gubbins. The original code is available from
 http://fastml.tau.ac.il/source.html and should be your first port of call. To
 modify the original code, or use parts of it for other purposes, permission
 should be requested. Please contact Tal Pupko: t...@post.tau.ac.il

the fastml author needs to be contacted.  I wonder whether you got a
permission from the author for using it in Gubbins.  It would be great
to hear that Gubbins is not fully depending from fastml2 and this code
might provide only some extra functionality that in worst case could be
skipped.  In any case it might make sense to discuss the license of
fastml with its author - may be he might consider a really free license
which would relax things.  One of the results would be that we could
provide an official Debian package of fastml / fastml2.

I found another issue with DendroPy which is listed in the file
INSTALL.md as

   * DendroPy ( >=3.11.1 )

While I noticed that this is not part of the (Build-)Depends in the
Debian packaging I started to package it in python-dendropy[3] and
sended a mail about test failures to its authors[4].  When ignoring the
test failures of the python-dendropy and building the packages anyway to
enable a build of Gubbins I noticed the following issue in the test
suite of Gubbins that is most probably connected to the fact that
official DendroPy has released a new major version (4.0.2).  I've just
attached the output of the test suite to this mail and may be you could
comment on this.

BTW, the current Debian policy is to refuse software that is Python 2
only.  So it would be great if you could either fully migrate to Python
3 or provide support for both Python versions.  I have made good
experiences with the script 2to3 to do the Python2 -> Python3
conversion.  Please let us know if you are interested in doing this but
might need any help.

Kind regards for providing Gubbins as Free Software

      Andreas.
