[Debian-med-packaging] Bug#944898: FTBFS: missing build-dependency python3-setuptools-scm

[Hans Joachim Desserud]

Source: python-dnaio
Version: 0.4-1
Severity: serious

Dear Maintainer,

python-dnaio currently fails to build from source with the following 
error message:
No local packages or working download links found for setuptools_scm
Traceback (most recent call last):
   File "setup.py", line 86, in <module>
     "Topic :: Scientific/Engineering :: Bio-Informatics"
   File "/usr/lib/python3/dist-packages/setuptools/__init__.py", line 
144, in setup
     _install_setup_requires(attrs)
   File "/usr/lib/python3/dist-packages/setuptools/__init__.py", line 
139, in _install_setup_requires
     dist.fetch_build_eggs(dist.setup_requires)
   File "/usr/lib/python3/dist-packages/setuptools/dist.py", line 720, in 
fetch_build_eggs
     replace_conflicting=True,
   File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 
782, in resolve
     replace_conflicting=replace_conflicting
   File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 
1065, in best_match
     return self.obtain(req, installer)
   File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 
1077, in obtain
     return installer(requirement)
   File "/usr/lib/python3/dist-packages/setuptools/dist.py", line 787, in 
fetch_build_egg
     return cmd.easy_install(req)
   File 
"/usr/lib/python3/dist-packages/setuptools/command/easy_install.py", 
line 698, in easy_install
     raise DistutilsError(msg)
distutils.errors.DistutilsError: Could not find suitable distribution 
for Requirement.parse('setuptools_scm')
E: pybuild pybuild:341: clean: plugin distutils failed with: exit 
code=1: python3.7 setup.py clean

(see 
https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/python-dnaio.html 
for more details)

After adding `python3-setuptools-scm` to build-depdendencies it built 
successfully in pbuilder on my local system.
