Obfuscated build logs are not very helpful. :|

Here's an actual build log snippet for i386:

| dh_auto_build
| running build
| running build_py
| creating build
| creating build/lib.linux-i686-2.7
| creating build/lib.linux-i686-2.7/pysam
[...]
| + env PYTHONPATH=/build/python-pysam-fLMqAQ/python-pysam-0.7.5/build/lib.linux-i486-2.7 ./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

So setup.py installed stuff to "build/lib.linux-i686-2.7", but 
PYTHONPATH is set to "build/lib.linux-i486-2.7".

/usr/share/python/python.mk defines a macro for determining build 
directory. You might want to use it. :)
