[Python-apps-team] Bug#742760: please make version comparison more robust for Cython

[Yaroslav Halchenko]

Package: s3ql
Version: 2.7-1
Severity: serious
Justification: fails to build from source (but built successfully in the past)

Currently would fail to build due to snapshot versioned release of cython

python3 setup.py build_cython
running build_cython
Traceback (most recent call last):
  File "setup.py", line 331, in <module>
    main()
  File "setup.py", line 189, in main
    command_options={ 'sdist': { 'formats': ('setup.py', 'bztar') } },
  File "/usr/lib/python3.3/distutils/core.py", line 148, in setup
    dist.run_commands()
  File "/usr/lib/python3.3/distutils/dist.py", line 930, in run_commands
    self.run_command(cmd)
  File "/usr/lib/python3.3/distutils/dist.py", line 949, in run_command
    cmd_obj.run()
  File "setup.py", line 213, in run
    cython_ver = [ int(x) for x in Cython.__version__.split('.') ]
  File "setup.py", line 213, in <listcomp>
    cython_ver = [ int(x) for x in Cython.__version__.split('.') ]
ValueError: invalid literal for int() with base 10: '1post0'
