[Debian-med-packaging] Bug#739631: python-pysam: FTBFS: ImportError: No module named pysam

[Aaron M. Ucko]

Source: python-pysam
Version: 0.7.5-1
Severity: serious
Justification: fails to build from source

Builds of python-pysam in minimal environments (as on the
autobuilders) have been failing:

  dh_auto_test
  chmod a+x tests/pysam_test_offline.py
  set -e -x;\
      for pyv in `pyversions -dv` ; do \
          cd tests && env PYTHONPATH=/«PKGBUILDDIR»/build/lib.«ARCH»-${pyv} ./pysam_test_offline.py ; \
  	done
  + pyversions -dv
  + cd tests
  + env PYTHONPATH=/«PKGBUILDDIR»/build/lib.«ARCH»-2.7 ./pysam_test_offline.py
  Traceback (most recent call last):
    File "./pysam_test_offline.py", line 8, in <module>
      import pysam
  ImportError: No module named pysam
  make[1]: *** [override_dh_auto_test] Error 1
  make[1]: Leaving directory `/«PKGBUILDDIR»'
  make: *** [build-arch] Error 2

Could you please take a look, and ensure that PYTHONPATH covers
pysam's Python files, not just the extensions that support them?

Thanks!
