Package: python-lesscpy
Severity: serious

Hello Thomas, Julien and Mehdi,

trying to build python-lesscpy in a clean environment with sbuild fails for
multiple reasons:

1. dh_auto_clean tries to run pyversions, which is not installed due to a 
missing build-dependency on python-minimal:

dpkg-buildpackage: source package python-lesscpy
dpkg-buildpackage: source version 0.9h-1
dpkg-buildpackage: source distribution experimental
 dpkg-source --before-build python-lesscpy-0.9h
dpkg-buildpackage: host architecture amd64
 fakeroot debian/rules clean
make: pyversions: Command not found
py3versions: no X-Python3-Version in control file, using supported versions
dh clean --buildsystem=python_distutils --with python3
   dh_testdir -O--buildsystem=python_distutils
   dh_auto_clean -O--buildsystem=python_distutils
dh_auto_clean: failed to run pyversions
make: *** [clean] Error 2
dpkg-buildpackage: error: fakeroot debian/rules clean gave error exit status 2

2. Even when installing python-minimal, the build fails because there is a
utf-8 encoded character in the LICENSE file:

Traceback (most recent call last):
  File "setup.py", line 27, in <module>
    license=open('LICENSE').read(),
  File "/usr/lib/python3.3/encodings/ascii.py", line 26, in decode
    return codecs.ascii_decode(input, self.errors)[0]
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 20: ordinal not in range(128)
make[1]: *** [override_dh_auto_install] Error 1

I don't know if this needs fixing in Debian at all, due to arch:All packages
being built on the developer's machine only, where most likely utf-8 is
available, but in Ubuntu for example, all packages are built on the build
farm, making this package unbuildable there.

Cheers,
   Andreas
