[Debian-med-packaging] Bug#742691: please make robust against ad-hoc (pre/post released) versions of cython

[Yaroslav Halchenko]

Package: python-biom-format
Version: 1.2.0-1
Severity: serious
Justification: fails to build from source (but built successfully in the past)

With yesterday's upload of snapshot of cython package (was needed to take care
about compatibility with python3.4) python-biom-format would fail to build:

dh_auto_clean
Traceback (most recent call last):
  File "setup.py", line 34, in <module>
    cy_version = tuple(map(int, Cython.__version__.split('.')))
ValueError: invalid literal for int() with base 10: '1post0'
dh_auto_clean: python setup.py clean -a returned exit code 1
make[1]: *** [override_dh_auto_clean] Error 1
make[1]: Leaving directory `/tmp/buildd/python-biom-format-1.2.0'
make: *** [clean] Error 2


you could probably simply use standard means such as LooseVersion to compare

python -c 'from distutils.version import LooseVersion as LV; print LV("0.20.1post0") >= LV("0.20.1")'
