Bug#708138: lintian: python-script-but-no-python-dep should accept python3.3



Package: lintian
Version: 2.5.10.4
Severity: normal

This may be somewhat similar to bug#673734.

I had script started as:
#!/usr/bin/python3

The python3 setup.py with dh --with python3 seems to convert this to:
#! /usr/bin/python3.3
(Please note space.)

I guess, it substitute with the current default python version 3.3
chosen by the python3 package.

Anyway, I get lintian ERROR with somewhat strange texts with my 
package debmake in NEW.

For dh --with ..., we should use python2 for python 2 series and python3 for
python 3 series. dh_pysupport or dh_pycentral are history.

I have "Depends: python3" in binary and get the following.  This seems to
limit only to python and do not accept python3 variants.

(The same result with version of lintian in testing/sid=2.5.10.5 too)

$ lintian -i debmake_4.0.0-1_amd64.changes

N: 
N:    Packages with Python scripts should depend on the package python. Those
N:    with scripts that specify a specific version of Python must depend on
N:    that version of Python (exactly).
N:    
N:    For example, if a script in the package uses #!/usr/bin/python, the
N:    package needs a dependency on python. If a script uses
N:    #!/usr/bin/python2.6, the package needs a dependency on python2.6. A
N:    dependency on python (>= 2.6) is not correct, since later versions of
N:    Python may not provide the /usr/bin/python2.6 binary.
N:    
N:    If you are using debhelper, adding ${python:Depends} to the Depends
N:    field and ensuring dh_pysupport or dh_pycentral are run during the build
N:    should take care of adding the correct dependency.
N:    
N:    In some cases a weaker relationship, such as Suggests or Recommends,
N:    will be more appropriate.
